Altum Peruensis Angelfish (Pterophyllum scalare) - UK

The Altum Peruensis Angelfish is one of the most elegant choices for aquarists who want striking height, calm authority, and carefully chosen angelfish tank mates in a South American display. Although sold under the Altum Peruensis name, this fish is best understood within the Pterophyllum scalare group kept in the hobby, combining the tall profile people love with the adaptable nature that makes aquarium angelfish UK keepers return to them again and again. In the right setup, these fish reach an impressive angelfish size of 15-20cm tall-bodied, with long trailing fins, a graceful midwater swimming style, and an angelfish lifespan and size balance that rewards patient fishkeepers for 7-10 years. See our detailed photos showing body depth, finnage, and the kind of shape that makes this an Angel Fish Altum Peruensis Angelfish for large aquarium layouts rather than cramped community tanks.

If you are researching angelfish tank size, angelfish temperature, angelfish water temperature, or the best angelfish tank setup, this guide covers the practical details that matter: tall aquariums, soft to moderately soft water, stable heat, and tank mates large enough not to be mistaken for food. These fish are often chosen by aquarists who want one of the most colourful angelfish styles without sacrificing classic wild elegance. With the right angelfish aquarium care, suitable decor, and sensible stocking, they become a centrepiece fish that feels both refined and full of personality.

Where Do Altum Peruensis Angelfish Come From? Natural Habitat Explained

The wider freshwater angelfish origin story begins in the Amazon basin of South America, including Peru, Brazil, Colombia, Guyana, and Suriname. Their natural range includes slow-moving tributaries, flooded forest edges, and areas with submerged roots, overhanging branches, and vertical plant stems. This freshwater angelfish habitat explains why they feel secure in tall tanks with layered decor rather than open, bare aquariums.

In the wild, freshwater angelfish in the wild feed on small crustaceans, insect larvae, worms, and tiny fish they can swallow. That natural hunting instinct is why many keepers asking what small fish can live with angelfish get into trouble with very tiny tetras or guppies. The classic angelfish habitat is warm, slightly acidic, and often tea-stained by tannins, with gentle current and lots of visual barriers. These are not pond fish, so questions like could koi angelfish live in a pond, would koi angelfish live in a pond, or koi angelfish in pond have the same answer here: no, angelfish are tropical cichlids that need stable indoor heat and protection from temperature swings.

Many hobbyists also search for angelfish wild type traits when they want a more natural look. Altum Peruensis-style fish appeal to that taste because they carry a taller, more refined silhouette and a subtler, riverine presence than some heavy domestic strains. If you are planning an angelfish in planted tank display, think Amazon swords, trailing roots, shaded corners, and driftwood that creates vertical structure. That style does more than look good; it supports calmer behaviour, better colour, and more confident feeding.

How to Set Up the Perfect Tank for Altum Peruensis Angelfish

Getting the angelfish aquarium requirements right starts with one simple rule: think tall before you think wide. These fish are deep-bodied cichlids with long fins, so the best angelfish aquarium setup ideas always include vertical swimming room. For a single pair, the angelfish minimum tank size is 200 litres, but for a proper group and safer social dynamics, a realistic freshwater angelfish tank size is 300 litres or more. If you are comparing with searches like angelfish tank mates 20 gallon, angelfish tank mates in a 30 gallon, or angelfish tank mates 40 gallon, those smaller tanks are not suitable for Altum Peruensis adults long term.

Tank Size Requirements

The most common mistake with angelfish tank size is focusing on litres alone and ignoring height. A tall 200-litre aquarium works far better than a shallow 200-litre tank. For a group of 5-6 juveniles growing out together, or for mixed angelfish freshwater tank mates, a 300-litre aquarium is the safer recommendation. Searches such as angelfish tank mates 55 gallon, angelfish tank mates 60 gallon, and angelfish tank mates 75 gallon are much closer to the mark, especially once the fish mature and begin establishing pecking order.

Water Parameters

The ideal angelfish water parameters for this fish are stable rather than extreme: 24-30°C, pH 6.0-7.4, and low to moderate hardness from 0-15 dGH. If you are checking angelfish temperature requirements, aim for 26-28°C for general care, with 27°C being an excellent day-to-day target. That range also fits angelfish care temperature, freshwater angelfish ideal temperature, and most mixed South American communities. Keepers often ask about angelfish water hardness and angelfish ideal water conditions; softer water tends to support better finnage and breeding behaviour, but consistency matters more than chasing a perfect number.

Filtration

Use filtration that gives high biological capacity without blasting the fish around. A large external canister or oversized internal filter works well, especially if the outlet is directed to diffuse flow along the back wall. Angelfish dislike harsh current, but they do need clean, oxygenated water. For heavily stocked community aquariums, pair strong biofiltration with weekly 30-40% water changes.

Substrate, Plants and Decor

Fine sand or smooth dark gravel suits the Amazon look and helps the fish feel secure. Broad-leaved plants such as Amazon swords are especially useful because they provide shelter and can even become spawning sites. Driftwood, upright branches, and tall background planting create the best angelfish tank setup for both display and behaviour. If you enjoy different domestic forms, a mixed angel display can include visually contrasting fish such as Koi Angelfish, Smoke Angelfish - Pterophyllum Scalare -, and Dalmatin Angelfish Pterophyllum Scalare South Stunning, but only in a large enough aquarium with line-of-sight breaks.

Lighting Requirements

Moderate lighting is ideal. Very bright, exposed tanks can make new angels nervous, while dimmer lighting over dark decor often brings out richer pattern contrast. In a planted aquarium, run lights for 7-9 hours daily and provide shaded zones with floating cover or taller leaves.

What Do Altum Peruensis Angelfish Eat? Complete Feeding Guide

A proper angelfish feeding guide starts with understanding that these are omnivores with a strong taste for meaty foods. The ideal freshwater angelfish diet combines quality cichlid flakes or granules with frozen foods such as bloodworm, brine shrimp, daphnia, and mosquito larvae. If you have searched what do koi angelfish eat, what koi angelfish eat, or what to feed koi angelfish, the answer is essentially the same for Altum Peruensis-style angels: varied, protein-rich, but not greasy or oversized foods.

Staple Foods

The best daily angelfish diet is a high-quality tropical granule or slow-sinking cichlid pellet sized for the mouth. This gives reliable nutrition without excessive waste. A balanced angelfish food type should include fish protein, crustacean meal, vitamins, and some plant matter.

Supplemental Foods

Offer frozen or live foods 3-4 times per week for condition and colour. This is especially useful before breeding and for newly imported fish that need encouragement to feed. Hobbyists often ask what time koi angelfish eat, what time koi angelfish can eat, or when koi angelfish eat; in practice, angelfish do best with two small meals a day at consistent times, such as morning and early evening.

Treats and Special Foods

Treats like brine shrimp and black mosquito larvae help bring fish into breeding condition and can intensify contrast in the body bars. If a fish is shy, feeding at the same place and time each day helps it learn the routine. Queries like what day koi angelfish eat and what day koi angelfish eat food reflect a common beginner worry, but healthy angelfish should feed daily once settled.

Do Angelfish Eat Algae, Plants, or Other Fish?

People often ask do freshwater angelfish eat algae, do freshwater angelfish eat plants, and do freshwater angelfish eat other fish. They are not algae specialists, they usually do not damage healthy plants, but yes, they may eat very small fish if they can catch them. That is why nano species and guppy fry are risky choices.

Time	Food	Amount
Morning	Quality angelfish granules	What they finish in 60-90 seconds
Evening	Frozen brine shrimp, bloodworm, or daphnia	Small portion, no leftovers after 2 minutes

What Does Altum Peruensis Angelfish Look Like? Colors, Patterns & Varieties

The first thing most keepers notice is the height. Adult angelfish size is not just about body length; it is the full silhouette, including dorsal and anal fin extension, that gives these fish their dramatic look. In a mature specimen, the body is laterally compressed, triangular in outline, and capable of turning side-on to roots and leaves in a way that mirrors wild river fish.

When people search angelfish colors, angelfish color types, and angelfish colour varieties, they are often comparing domestic strains with more natural forms. Altum Peruensis fish tend to appeal to aquarists who prefer the elegance of silver, bronze, olive, and dark vertical barring over heavy marbling. They may not always be the loudest of the most colourful angelfish types, but in the right lighting they are among the most graceful. Our photos show the clean body profile and refined finnage that many hobbyists consider the prettiest angelfish style for a biotope-inspired aquarium.

If you are trying to judge difference between angelfish male and female, it is difficult outside breeding condition. Females usually show a broader ovipositor before spawning, while males often develop a slightly more pointed breeding papilla, but body shape alone is unreliable. For buyers comparing morphs, you may also enjoy looking at Platinum White Angelfish - Pterophyllum Scalare for a bright modern contrast or Koi Angelfish if you prefer bold orange-and-white domestic colouration.

What Fish Can Live With Altum Peruensis Angelfish? Compatibility Guide

This is the question most buyers ask first, and for good reason. The best angelfish tank mates are calm, medium-sized fish that enjoy similar warm water and will not nip fins. If you are searching what fish can be mixed with angelfish or good companion fish for angelfish, think in terms of size, temperament, and feeding level. Angelfish are not hyper-aggressive, but they are cichlids, and they can become territorial as they mature or pair off.

Ideal Tank Mates

Excellent altum angelfish tank mates include larger tetras, Corydoras, Bristlenose Plecos, peaceful loaches, and some calm dwarf cichlids. Questions like cory catfish angelfish and bristlenose pleco and angelfish come up often because both combinations work well in a tall South American setup. Corydoras occupy the bottom, plecos handle surfaces, and angelfish keep to the midwater. Schooling fish for angelfish tank should be deep-bodied or large enough not to be eaten, such as adult cardinals in a spacious tank, larger rasboras, or robust tetras.

Bolivian rams are another popular option, so the short answer to bolivian ram angelfish is yes, usually compatible in a sufficiently large, warm, structured aquarium. Kuhli loach angelfish can also work, especially in planted tanks with plenty of hiding places, and the same goes for zebra loach with angelfish if the loaches are not overly boisterous. Some keepers ask about rainbow kribs angelfish; that pairing is more situational, as kribs can become quite territorial when breeding.

If you want to compare angelfish strains for a community display, browse Dalmatin Angelfish Pterophyllum Scalare South Stunning, Smoke Angelfish - Pterophyllum Scalare -, and Blue Diamond Angelfish. Tropical Fish. These can all be considered when building an Angel Fish Altum Peruensis Angelfish for community tank around similar-sized angels rather than mixed species.

Species to Avoid

The worst choices on an angelfish compatibility chart are fin nippers and tiny fish. Tiger barbs, serpae tetras, and similar nippy species can shred long fins. Neon tetras, endlers, and very small guppies may be treated as food, which answers the common search angelfish tank mates guppy: adult guppies may survive for a while, but it is not a dependable match. Bad tank mates for angelfish also include goldfish, because the temperature and water quality needs are completely different, so angelfish tank mates goldfish is a firm no. The same caution applies to highly aggressive cichlids and coldwater species.

Questions such as silver dollar angelfish and can angelfish live with mollies need nuance. Silver dollars grow large and are fast, messy feeders, so they are not ideal in most home setups. Mollies can work only if water chemistry is a compromise and the mollies are not nippy, but angelfish generally do best in softer, less alkaline conditions than mollies prefer.

Tank Size and Stocking Examples

For angelfish tank mates 55 gallon, a sensible plan is one adult pair or 4-5 subadults with a shoal of larger tetras and a bottom group of Corydoras. For angelfish tank mates 75 gallon, you have room for 5-6 angels, 12-20 suitable schooling fish, and bottom dwellers. Searches for angelfish tank mates 29 gallon or angelfish tank mates 20 gallon usually end in disappointment because adult angels simply outgrow those volumes.

Invertebrates

The best shrimp to keep with angelfish are large Amano shrimp in heavily planted tanks, and even then there is some risk. Small cherry shrimp are usually viewed as food. Nerite and mystery snails are safer choices than dwarf shrimp if you want invertebrates in the tank.

Species	Compatible?	Notes
Koi Angelfish	✅ Yes	Works in large groups if all fish are similar size and the tank is tall
Corydoras catfish	✅ Yes	Excellent bottom-dwelling companions in warm, clean water
Neon tetra	❌ Avoid	Often too small once angelfish mature

How Do You Breed Altum Peruensis Angelfish? Complete Breeding Guide

Angelfish breeding is moderate rather than difficult, but success depends on water quality, pair selection, and patience. If you have wondered are angelfish better in pairs, the best approach is usually to raise a small group and let a pair form naturally. Forced pairs often fight. This applies whether you are researching freshwater angelfish breeding, koi angelfish breeding, or how to manage a koi angelfish breeding pair.

Breeding Setup

Use a dedicated tall tank of at least 100-150 litres for a pair, with a sponge filter, heater set around 27-28°C, and broad leaves or vertical spawning slates. Slightly softer, slightly acidic water often triggers courtship. If you are asking how to breed koi angelfish, the environmental cues are very similar: warmth, stable water, and high-quality conditioning foods.

Spawning Behaviour

Before spawning, the pair cleans a vertical surface and becomes more territorial. This is when the difference between angelfish male and female becomes easier to spot because the female’s ovipositor is broader. For anyone asking do freshwater angelfish lay eggs, yes, they are egg layers and usually deposit neat rows of adhesive eggs on leaves, pipes, or slates.

Egg Care and Hatching

Angelfish eggs care involves clean water, gentle aeration, and protection from fungus. Parents may guard the spawn well, but young pairs sometimes eat their first few clutches. Freshwater angelfish eggs usually hatch in about 48-72 hours depending on temperature, and the wrigglers remain attached while absorbing their yolk. If you are researching freshwater angelfish eggs stages or freshwater angelfish eggs hatching stages, expect eggs, wrigglers, then free-swimming fry within roughly 5-7 days from spawning.

Fry Care

Angelfish babies care starts with newly hatched brine shrimp, microworms, or commercial fry foods once the fry are free swimming. Feed small amounts 4-5 times per day and maintain pristine water with gentle daily changes. Questions like what day koi angelfish have babies reflect timing concerns, but the exact schedule depends on temperature and whether the pair is settled.

Common Health Problems in Altum Peruensis Angelfish & How to Prevent Them

Healthy angelfish hold their fins open, feed eagerly, maintain clear eyes, and show steady balance in the water. If you are researching angelfish common diseases, common angel fish disease, or freshwater angelfish diseases, most problems trace back to stress, poor water quality, sudden temperature swings, or unquarantined new arrivals.

Common Diseases and Symptoms

White spot appears as tiny white grains and often follows stress or temperature instability. Fin rot shows as frayed or receding fins, especially after nipping or poor maintenance. Internal flagellates may cause stringy waste and weight loss. Bacterial infections can produce ulcers, cloudy patches, or lethargy. Although many people search for freshwater angelfish diseases with pictures, the safest response is to diagnose by symptoms plus water test results rather than internet photos alone.

Treatment and Prevention

Start with testing ammonia, nitrite, nitrate, and temperature. Correct water quality first, then isolate the fish if needed. Increase aeration during treatment and avoid mixing medications casually. Stable angelfish water parameters, a varied diet, and a proper quarantine routine prevent more problems than medicine ever cures.

What Is Altum Peruensis Angelfish Behaviour Like in the Aquarium?

Altum Peruensis angels are best described as calm, observant, and occasionally bossy. They spend most of their time in the midwater, often facing into gentle current or gliding through vertical decor. Juveniles are usually more social, while adults become more aware of hierarchy and territory. This is why a group often works better than random singles, provided the aquarium is large enough.

They are not frantic swimmers, which makes them a strong choice for aquarists who enjoy measured, graceful movement rather than constant activity. In a well-designed angelfish in planted tank layout, they weave between broad leaves and wood, often pausing under cover before moving out to feed. During breeding, they become more defensive and may drive away nearby fish from a chosen spawning site.

If you want natural behaviour, provide a tall tank, calm tank mates, and visual barriers. In bare or overcrowded tanks, they can become skittish or aggressive. In structured aquariums, they are among the best angelfish for beginners who are ready to move beyond nano fish and learn proper cichlid-style observation.
