Zebra Smoke Angelfish (Pterophyllum scalare)

The Zebra Smoke Angelfish is a domestic colour form of the freshwater angelfish, Pterophyllum scalare. Dark vertical zebra bars cross a silver-grey body while deeper smoke pigmentation develops toward the rear and through the fins. The result is a distinctive tall cichlid with the familiar angelfish silhouette and a more dramatic pattern than a standard silver form.

One selected quantity means one juvenile fish at the listed approximate 1 cm dispatch grade. This is a very small starting size, not the adult measurement. Plan for a fish that can reach about 15 cm in body length and commonly around 20-25 cm in total height when the dorsal, anal and ventral fins are extended. Price and availability must always be read from the live purchase controls rather than descriptive text.

This variety needs a mature, warm aquarium with excellent water quality and genuine vertical room. Use about 200 litres, at least 100 cm of length and roughly 50 cm of water height as a conservative long-term floor for one adult centrepiece or a compatible established pair. A juvenile group or a substantial community needs more space, commonly 300 litres or above, plus a plan for territorial changes as fish mature and pairs form.

What you receive at the 1 cm grade

The displayed size is the approximate dispatch grade for the fish on this page. Living fish naturally vary a little, so treat 1 cm as a juvenile indication rather than a millimetre-exact promise. At this stage the body, fins, bars and smoke coverage are still developing. Pattern contrast may strengthen or change as the fish grows.

A 1 cm angelfish needs finely sized food, gentle competition and especially stable water. It must not be placed directly with adult angelfish, large predatory fish or any companion capable of swallowing or intimidating it. A mature grow-out environment can be useful, but the permanent adult aquarium should already be part of the plan. Juvenile size never makes a small tank an acceptable long-term home.

How to plan for this juvenile fish

Decision	At approximately 1 cm	Adult plan
Food	Fine crumb, micro-granules and very small frozen or live foods	Quality angelfish or cichlid granules with varied frozen and live foods
Tank mates	Only gentle fish too small to threaten it and large enough not to be future prey	Medium peaceful species that tolerate a territorial cichlid
Filtration	Mature, clean and intake-safe with gentle local flow	Strong biological capacity without blasting the tall fins
Space	A secure grow-out setup may be used temporarily	About 200 litres, 100 cm length and 50 cm water height as a conservative floor
Social plan	Juveniles can be grown in a group where capacity permits	Monitor hierarchy and separate or rehome fish if pairs become territorial

One quantity buys one fish, not a pair or group. If you are building a juvenile group, choose the number only after calculating the adult capacity and a backup plan. The tank-volume tool and stocking calculator can organise the first draft, but neither replaces observation of hierarchy, filtration and usable vertical space.

Why the scientific name is Pterophyllum scalare

Pterophyllum scalare is the species. Zebra and Smokey are established domestic pattern traits, and Zebra Smoke is the commercial morph name used for fish showing both characteristics. Appending those morph words to the binomial as though they formed a three-part scientific name incorrectly turns a colour description into taxonomy.

The distinction helps buyers and search systems understand the product. Someone comparing freshwater angelfish species needs to know that this is not Pterophyllum altum or Pterophyllum leopoldi. Someone comparing colour forms needs the separate Zebra Smoke name. The corrected title therefore keeps both: Zebra Smoke Angelfish identifies the domestic form, while Pterophyllum scalare identifies the species.

Names and claims used on this listing

Angelfish patterns can look darker or paler with age, lighting, social state and stress. The Zebra and Smokey traits are real domestic phenotypes, but this retail name is not a laboratory genotype certificate. We do not promise an exact allele combination, bar count, smoke boundary or future colour intensity for an individual juvenile.

Appearance, growth and adult proportions

The species has a laterally compressed, triangular body with an arched forehead, high dorsal and anal fins, thread-like ventral fins and a relatively short tail. The Zebra Smoke form overlays that silhouette with several dark vertical bars and a smoky grey-to-black wash, often strongest through the rear body and fins. Orange-red eyes, silver areas and subtle blue or bronze reflections may become visible under balanced aquarium lighting.

Body length is only part of the space requirement. A normal adult may reach about 15 cm from nose to tail, while extended dorsal and anal fins make the fish much taller. Around 20-25 cm of total height is a sensible planning figure for a well-grown standard-fin specimen. That is why water depth matters: an adult should be able to hold and turn with fins open rather than constantly folding them near the substrate or surface.

Growth depends on genetics, food, temperature, water quality, stocking pressure and early rearing. Frequent heavy feeding without enough water maintenance does not create healthy growth; it creates waste and chronic stress. Small varied meals, clean warm water and enough room are more reliable. Judge progress by balanced body condition, open fins, steady growth and normal behaviour rather than trying to force a particular size by a deadline.

Mature males and females are difficult to distinguish outside breeding condition. Head shape, body depth and fin form are inconsistent clues. The breeding papilla becomes more useful around spawning, but this 1 cm juvenile cannot be sold with a reliable sex. The gallery also represents the morph and aquarium context rather than guaranteeing the exact dispatched individual.

Natural background and domestic strain needs

The wild ancestors of Pterophyllum scalare occur across the Amazon basin and connected waters in Peru, Colombia, Brazil, French Guiana and Guyana. They live among dense aquatic or flooded vegetation, roots and branches in warm freshwater. Their deep, compressed bodies move between vertical stems, while their hunting behaviour is suited to small crustaceans, insect larvae and fish.

Zebra Smoke Angelfish are domestically bred rather than collected as this named form from the wild. Selective breeding changes the visible pattern, but not the fundamental needs of a tall South American cichlid. Warm stable water, visual barriers, open turning room, a mature filter and appropriately sized companions remain essential.

A useful layout combines tall plants or vertical wood at the back and sides with an open middle. Amazon swords, Vallisneria and tall Cryptocoryne provide structure; Java fern and Anubias can be attached to wood. Keep sharp rock and narrow traps away from the long ventral and unpaired fins. A shaded area reduces visual pressure, while moderate open light lets you inspect posture, skin and feeding response.

The wider freshwater angelfish care guide explains species-level husbandry, and the Angelfish collection helps compare this morph with other P. scalare forms. Those comparisons should focus on starting size, fin shape, pattern and availability; the core adult welfare requirements remain broadly similar.

Aquarium size, height and equipment

Use a tall, mature aquarium

For one adult centrepiece or a compatible established pair, plan around at least 200 litres, 100 cm of horizontal length and about 50 cm water height. This is a conservative retail recommendation rather than an invitation to fill every litre. Hardscape, substrate, other fish and the filter reduce practical capacity. A 300-litre or larger system is more appropriate for a juvenile group, several adult angelfish or a mixed community.

Angelfish can be territorial even when described as peaceful. More volume allows retreat, but shape and structure matter as much as litres. A tall aquarium with several visual breaks gives subordinate fish somewhere to leave the dominant fish's line of sight. A narrow decorative column may be tall yet offer too little horizontal separation.

Filtration and flow

Use a mature filter with enough biological media for the full adult stock. Canister filters, well-sized internal filters and carefully managed sponge systems can all work. The outcome should be zero measurable ammonia, zero measurable nitrite, low and stable nitrate, clear water and reliable oxygen exchange.

Angelfish appreciate clean oxygenated water but do not need a strong jet across every swimming route. Diffuse the return along the tank, use a spray bar if necessary and keep calmer areas behind plants or wood. At the 1 cm grade, cover or guard any intake powerful enough to trap the juvenile. Check protection as the fish grows rather than leaving restrictive mesh to clog.

Heating, cover and lighting

Use a reliable heater sized for the actual water volume and monitor it with a separate thermometer. A lid limits evaporation, prevents access by pets and reduces sudden temperature loss. Angelfish are not famous jumpers in the way danios are, but any startled fish can leave an uncovered tank. Moderate lighting on a consistent day-night schedule suits both fish and common planted layouts.

Pre-order aquarium readiness check

Area	Ready when	Risk to avoid
Cycle	Ammonia and nitrite remain at 0 mg/L under a proven biological load	Using a newly filled aquarium for a tiny juvenile
Height	About 50 cm water depth is available for adult fins	Counting litres while ignoring the adult vertical profile
Filter intake	The juvenile cannot be trapped or drawn against it	Assuming a standard guard is safe for a 1 cm fish
Flow	Water circulates without forcing the fish to fight a current continuously	Directing a high-output return through the only open area
Decor	Vertical cover and open turning space are both present	Sharp rock, dense clutter or narrow fin traps
Backup plan	A divider, spare mature system or rehoming option exists for serious aggression	Assuming every juvenile group will remain socially stable

If this is your first warm freshwater setup, start with the first tropical aquarium guide. Cycle completion is measured by water chemistry, not by waiting an arbitrary number of days.

Water parameters and maintenance

Keep this domestic angelfish at 24-28°C, pH 6.0-7.8 and roughly 3-15 dGH. Published species records extend to 30°C, pH 8.0 and a somewhat broader hardness range, but the narrower retail range gives a practical overlap for long-term community care. Stability is more important than forcing every value toward the centre.

Water targets and practical management

Measure	Working target	What matters
Temperature	24-28°C	Keep changes gradual and make sure every companion shares the range
pH	6.0-7.8	Use stable source water where possible; avoid repeated quick chemical correction
General hardness	About 3-15 dGH	Test the source and match species to the actual water
Ammonia	0 mg/L	Any reading requires an immediate investigation
Nitrite	0 mg/L	Juvenile angelfish are particularly vulnerable to an immature biofilter
Nitrate	Low and stable	Control with sensible stocking, measured feeding and regular water changes
Oxygen	Well oxygenated	Maintain surface movement without excessive local current

Change a consistent portion of water every week, commonly around 25-40% depending on measured nitrate, stocking and feeding. Match replacement temperature, use a suitable dechlorinator and avoid exposing the juvenile to a sudden pH or conductivity shift. Siphon waste from open areas while leaving useful biological surfaces intact.

Rinse mechanical filter media when flow declines, using removed aquarium water where appropriate. Do not replace all biological media at once or deep-clean every surface on the same day. A visually spotless aquarium can still be biologically unstable. The water chemistry guide explains ammonia, nitrite, nitrate, pH and hardness in more detail.

Watch the fish as well as the test kit. Rapid breathing, clamped fins, dark stress colour, hanging near the surface or loss of appetite can signal poor water, aggression or illness. A 1 cm juvenile has little margin for chronic competition, so investigate early instead of waiting for weight loss.

Temperament, groups and pair formation

Freshwater angelfish are cichlids. They often move calmly and can live in a well-planned community, but they are not automatically peaceful with every fish. Juveniles may gather loosely; adults establish hierarchy, and a pair can defend a spawning surface and surrounding space. Short displays are normal. Relentless chasing, torn fins or one fish pinned in a corner is not.

There are three workable social approaches. One adult can be kept as a centrepiece in a compatible community. A proven compatible pair can occupy a suitable tall aquarium. Alternatively, five or six juveniles may be grown together in a much larger system so pairs can form naturally, provided the keeper can separate or rehome fish as territories develop.

Buying exactly two young angelfish does not guarantee a pair. They may be the same sex or simply incompatible. The listing therefore promises neither sex nor pair status. If the aim is a breeding pair, allow natural selection from a properly sized juvenile group or obtain a genuinely established pair from a source that sells it as such.

Rearranging a limited amount of decor can interrupt territories, but it is not a cure for insufficient space. A divider or separate mature aquarium may be needed. Do not wait for severe injury before acting.

Feeding a 1 cm juvenile and an adult

Pterophyllum scalare is an omnivore with a predatory appetite for small aquatic animals. In the aquarium, use a quality angelfish or cichlid micro-granule, fine flake or soft crumb as the staple, supported by appropriately sized frozen or live foods. Daphnia, baby brine shrimp, mosquito larvae and similar foods provide variety when their size and source are safe.

At approximately 1 cm, offer two or three very small meals daily if the mature filter and maintenance routine can support them. Food particles must be small enough to swallow. Spread them where the juvenile can feed without entering a strong current or competing with much larger fish. Remove obvious leftovers and reduce the next portion rather than allowing food to decay.

As the fish grows, move gradually to small granules or pellets, flakes and larger frozen foods. Adults usually do well on one or two measured meals daily. A varied diet supports body condition and pigmentation, but no food can guarantee a particular smoke boundary or bar intensity. Overfeeding causes fatty condition, digestive trouble and declining water quality.

Example feeding roles through growth

Food	Juvenile use	Adult use	Control point
Fine quality flake or crumb	Primary staple when crushed appropriately	Part of a varied staple rotation	Do not leave powder coating the substrate
Micro-granules	Useful measured staple	Replace with a size the adult swallows easily	Choose slow-sinking food and spread the feeding area
Baby brine shrimp	Growth and feeding-response food	Small enrichment food	Use a clean culture or reputable frozen product
Daphnia	Only suitably small forms	Useful frozen or live variety	Avoid unknown wild collection sites
Bloodworm and larger larvae	Usually too large at the 1 cm grade	Occasional varied food when appropriately sized	Not a complete staple and not an unlimited meal
Vegetable component	Provided through balanced prepared food	Spirulina-containing foods can add variety	Do not treat angelfish as algae-control fish

Observe every fish during feeding. A strong appetite is useful, but frantic hunger after every meal does not prove underfeeding. Use body shape, growth, waste and water tests to adjust the routine.

Angelfish tank mates and community planning

The best tank mates are peaceful, medium-sized fish that share warm water, do not nip long fins and are not small enough to become prey. Adult size matters in both directions. A companion that is safe beside a 1 cm juvenile may later fit into an adult angelfish's mouth; an adult community fish may injure the juvenile now.

Medium-bodied tetras and rasboras can work when fully grown, numerous enough for their own social needs and not habitual fin nippers. Corydoras may suit the lower level where their temperature and substrate requirements overlap. Bristlenose plecos can be compatible in a tank with wood, food access and adequate waste capacity. Peaceful dwarf cichlids are conditional because breeding territories can overlap.

Avoid neon-sized fish and tiny livebearer fry once the angelfish is large enough to hunt them. Shrimplets are likely prey, and even adult dwarf shrimp may be investigated. Tiger Barbs and other persistent fin nippers are poor choices. Aggressive cichlids, large predators and fish that demand very different water are unsuitable.

Community compatibility guide

Companion	Suitability	Conditions
Medium peaceful tetras	Often suitable	Use adult fish too large to swallow; avoid species known for fin nipping
Medium rasboras	Often suitable	Provide a proper shoal and enough midwater space for both groups
Corydoras	Conditional to good	Match temperature, use smooth substrate and keep a full Corydoras group
Bristlenose pleco	Often suitable	Provide wood, food, floor space and filtration for the combined waste load
Peaceful dwarf cichlids	Conditional	Use a larger structured tank and expect territorial overlap during breeding
Very small tetras, fry and shrimplets	Avoid as a long-term assumption	An adult angelfish is an opportunistic predator
Fin-nipping barbs	Avoid	Long dorsal, anal and ventral fins are vulnerable
Goldfish	Avoid	Temperature, feeding, waste and social needs do not align
Aggressive or large predatory cichlids	Avoid	Injury and chronic territorial stress are likely

Use the adult requirements of every species, not a generic community-fish label. Add social minimums, consider where each group feeds, and leave room for spawning territory. Our South American Cichlids collection helps compare different cichlids, but shared geography does not make every combination compatible.

Comparing Zebra Smoke with other angelfish forms

Colour forms share the basic needs of P. scalare, yet they create different visual effects. Zebra Smoke combines clear bars with a darker posterior wash. A standard Zebra Angelfish emphasises additional vertical striping without necessarily showing the same smoke coverage. A Smoke Angelfish may carry a broad dark rear pattern with less emphasis on zebra bars.

Angelfish form comparison for visual planning

Form	Main visual signal	Care difference
Zebra Smoke Angelfish	Strong vertical bars plus darker smoke through the rear body and fins	Use the species-level P. scalare care on this page
Zebra Angelfish	Multiple bold vertical bars over a lighter silver body	Compare the exact dispatch grade; adult welfare is broadly similar
Smoke Angelfish	Dusky posterior pigmentation and dark fins	Same species-level warm, tall-aquarium planning
Marble Angelfish	Irregular black-and-silver marbling	Pattern differs; core adult care remains P. scalare care
Platinum White Angelfish	Pale white-to-silver body with reduced dark pattern	Colour contrast differs; do not infer different water needs from colour alone
Full Orange Koi Angelfish	Orange, white and variable dark markings	Compare source size and individual listing; species-level care is similar

Do not choose several forms simply to collect colours unless the aquarium can support the adult social structure. Angelfish recognise territories and potential partners, not retail labels. One healthy centrepiece or a stable pair is better than a cramped assortment.

Breeding, sexing and parental care

Freshwater angelfish form pairs and lay adhesive eggs on a vertical surface such as a broad leaf, root, slate or filter pipe. Both parents may guard and fan the eggs, then protect wrigglers and free-swimming fry. Domestic fish vary in parental reliability, especially young pairs, and community tank mates often eat eggs or fry.

Sexing is unreliable at juvenile size. Around spawning, a female generally shows a broader, blunt ovipositor while the male's papilla is narrower. Forehead shape, fin length and general body outline are not dependable enough for a retail sex guarantee. This listing supplies one unsexed juvenile per quantity.

A breeding project needs more than two fish. Start with compatible mature adults, excellent water, a separate plan for pair territory, sponge-protected filtration and enough space to raise the young. Breeding pairs may attack former companions, so be ready to move fish. Fry need microscopic or very fine foods followed by baby brine shrimp, frequent small feeds and exceptionally careful water quality.

The Zebra Smoke morph name does not guarantee predictable offspring. Visible parents can carry unexpressed traits, and the exact genotype of this retail juvenile is not certified. Breed only if you can house the resulting fish responsibly and keep accurate records rather than promising a particular colour outcome.

Health, observation and common warning signs

A healthy juvenile holds itself upright, uses both sides of the body symmetrically, breathes steadily and responds to food. Fins should open between movements, eyes should be clear and the belly should not remain pinched. Temporary colour loss after transport can be normal, but posture and breathing provide more useful early information.

Signs to investigate promptly

Observation	Possible concern	First checks
Rapid breathing or surface hanging	Low oxygen, ammonia, nitrite, temperature or gill irritation	Test water immediately and increase safe gas exchange while finding the cause
Clamped fins and dark colour	Stress, poor water, bullying or disease	Review parameters, social pressure and visible symptoms
White grains on skin or fins	Possible white spot	Confirm the diagnosis before choosing a treatment
Frayed fins	Fin nipping, sharp decor, poor water or secondary infection	Inspect companions, equipment, decor and water quality
Pinched belly or weight loss	Food competition, unsuitable particle size, stress or internal disease	Observe feeding access and seek an evidence-based diagnosis
One-sided swimming or loss of balance	Injury, severe stress or systemic illness	Check water and arrange specialist advice promptly

Do not medicate automatically for every dark colour or closed fin. Correct husbandry faults first, identify the likely cause and follow product directions if treatment is genuinely required. Copper, salt, antibiotics and temperature changes are not interchangeable general cures. Some treatments affect plants, invertebrates or biological filtration.

Quarantine is the safest way to protect an established aquarium, but a 1 cm fish needs a mature, appropriately filtered quarantine system rather than a newly filled container. Use dedicated equipment, prevent intake injury and observe appetite, waste, breathing and skin before mixing populations.

Delivery day and acclimation

Prepare the aquarium before dispatch. Test temperature, ammonia, nitrite, nitrate and the practical pH or hardness overlap. Make sure the filter intake is juvenile-safe, the light can be dimmed and aggressive residents can be separated. Do not rearrange the whole aquarium while a small fish waits in a transport bag.

On arrival, inspect the sealed bag and follow the current livestock instructions supplied with the order. Temperature equalisation and water transfer must be handled carefully because transport water chemistry changes during the journey. Use the acclimation timer as a practical aid, while the order instructions remain the primary process.

Keep lights low after release and avoid a large first meal. Watch the juvenile from a distance so normal sheltering is not mistaken for failure. Confirm that it is not being drawn toward an intake or chased by larger residents. Offer a tiny, appropriately sized meal once it has settled and remove uneaten particles.

Eligible livestock orders are covered by the current UK delivery and Live Arrival Guarantee terms. Read those conditions before the delivery day so evidence and contact deadlines are understood. The guarantee protects eligible arrival issues; it does not replace a cycled aquarium, compatible stocking or correct acclimation.

How to read the product images

The existing gallery shows the Zebra Smoke pattern, adult-style proportions and several aquarium contexts. It helps identify the intended form: dark vertical bars, silver-grey areas and posterior smoke pigmentation on a tall freshwater angelfish. The images do not promise the exact fish, sex, body size, bar arrangement, fin length or colour intensity that will arrive.

This product starts at an approximately 1 cm juvenile grade, so the dispatched fish will be much smaller and less developed than an adult display image. Pattern expression can change as it grows. Stress, background, light angle and camera processing also affect how dark the smoke and bars appear. Use the gallery for morph recognition, not as a specimen contract.

Why order from Tropical Fish Co?

This listing separates the verified species, commercial morph, juvenile dispatch grade and adult care plan. That matters because a 1 cm angelfish is easy to underestimate. The page tells you what one quantity means, how large the fish can become, why tank height matters, and when a peaceful-looking cichlid can become territorial.

New customers can use WELCOME10 for 10% off an eligible first order under the current checkout terms. Eligible livestock orders also include the current Live Arrival Guarantee. Discounts, delivery eligibility, stock and price can change, so the live checkout and policy pages remain authoritative.

Browse the Angelfish collection to compare current forms and sizes, or use the Tropical Fish collection to plan a broader community. Purchase only when the mature aquarium, juvenile-safe intake, compatible residents and delivery-day schedule are ready.
