Spotted Panchax (Epiplatys dageti)

Spotted Panchax (Epiplatys dageti) is a small West African killifish that spends most of its time at or just below the water surface. It is also known in the aquarium trade as Red-Chinned Panchax, Redchin Panchax or Firemouth Panchax. The fish is sold here at species level as Epiplatys dageti. Older aquarium literature may add the name monroviae, but a particular locality or colour form is not guaranteed.

One selected quantity buys one unsexed fish in the chosen approximate dispatch size: 3–4 cm or 4–5 cm. It is not a pair, trio or group, and sex cannot be promised at these sizes. Adults reach about 6 cm total length. This is a social, surface-oriented species, so plan for a group of at least six rather than keeping one fish alone. A mature aquarium with a secure lid, subdued light, gentle filtration and plentiful floating cover is essential.

For routine care, use 21–24°C, pH 6.0–7.0 and 5–12 dGH. This practical range sits within the published species guidance and favours the slightly acidic, soft to moderately soft conditions associated with the fish. Stability, a fully cycled aquarium and zero ammonia or nitrite matter more than chasing a single decimal point.

Identity, name and what the fish should look like

Epiplatys dageti was described by Max Poll in 1953 and is placed in the order Cyprinodontiformes and family Nothobranchiidae. FishBase records the species from coastal West Africa, from the Monrovia area of Liberia through southern Cote d'Ivoire to south-western Ghana. It occurs in swampy coastal areas, quiet brook margins and slow-flowing lowland water. It is a non-annual killifish: its life cycle does not depend on eggs surviving a dry season in the way that annual killifish eggs do.

The common names need a little care. Redchin or Red-Chinned Panchax is widely used for fish in this species complex, especially forms with a yellow, orange or red throat. Historical aquarium literature also uses Epiplatys dageti monroviae, and specialist references describe variation in throat colour and vertical barring between populations. This product is identified at species level as Spotted Panchax, Epiplatys dageti. A named collection locality, subspecies, exact number of flank bars or particular intensity of red colour is not promised.

The expected body form is elongated with a flattened upper profile and an upturned mouth suited to taking food from the surface. Adults are usually brown, olive or bronze with vertical barring and subtle iridescence; mature males are generally more colourful and may develop more extended fins. Individual colour can change with age, sex, mood, lighting and holding conditions. The selected size option, not the gallery, is the guide to the approximate size dispatched.

The four gallery pictures are illustrations created with a real supplier reference image. They are useful for showing the general surface-dwelling body plan and aquarium context, but they are not photographs of the exact fish that will be sent and cannot prove its sex, locality, adult colour or precise markings.

Natural habitat and behaviour

Spotted Panchax comes from warm coastal lowlands where shaded swamps, pools, creeks and quiet river edges provide slow water and dense marginal vegetation. Floating leaves, overhanging plants, roots and submerged branches create a sheltered upper layer. That habitat explains the fish's level-backed silhouette, upturned mouth and habit of waiting beneath cover before darting at food.

In the aquarium, expect calm hovering punctuated by quick feeding strikes. This is not a fish that should race continuously around open water. A settled group patrols the surface, pauses beneath floating plants and moves between shaded stations. A sparse, bright or turbulent aquarium can leave the fish skittish and pressed into corners. A mature planted layout produces more natural movement and gives lower-ranking fish somewhere to leave another fish's view.

The species is gregarious rather than a tight schooling fish. Practical Fishkeeping recommends at least six specimens, while other specialist guidance suggests groups of six to eight or more. Males may chase or display to one another, especially as they mature, but serious harm is less likely when the group has enough room, several floating-cover zones and visual breaks. A single fish, an arbitrary pair or a small trio can concentrate social pressure and does not show the species at its best.

Every opening in the cover is a risk. Killifish are accomplished jumpers, and surface-oriented species can find surprisingly small gaps around cables, pipework and hang-on filters. Use a rigid lid or closely fitted cover glass, block openings safely and check the cover after maintenance. Floating plants can make the fish feel secure, but plants are not a substitute for a physical lid.

Aquarium size and group planning

A responsible aquarium plan must accommodate a proper social group and provide horizontal surface area. For a group of at least six, use an aquarium of about 80 cm length as a practical starting point, then choose the volume for that footprint, the group and any tank mates. More room is useful when the group contains several mature males or when the layout does not provide many separate shaded stations. A tall narrow aquarium is less useful than a longer one because most activity occurs near the surface.

A compact breeding aquarium has a different purpose from a permanent display. An experienced breeder may temporarily use a compatible pair or a trio of one male with two females in a mature spawning setup with a secure cover, gentle sponge filtration and plants or mops. The adults are then removed or the eggs collected. That short, supervised breeding arrangement does not replace the longer aquarium and group of at least six recommended for normal long-term care.

Before ordering, check all of these

• The aquarium is fully cycled, mature and large enough for at least six adults.
• The footprint is roughly 80 cm long or larger, with generous surface area.
• A rigid, close-fitting lid covers every escape gap.
• Ammonia and nitrite are zero, and nitrate is controlled by maintenance.
• Temperature, pH and hardness have been measured rather than assumed.
• Floating cover and broken sight lines are already established.
• Filtration is biologically effective without harsh surface current.
• Tank mates match the water, temperament and adult-size plan.
• Food that remains near the surface is available.
• A quarantine or observation plan is ready for new livestock.

Water parameters and filtration

Use 21–24°C for routine care. This range leaves room for normal seasonal variation while staying close to the cooler tropical conditions described across species references. Avoid prolonged overheating, and do not raise the temperature automatically when a fish appears unwell; first test water quality, oxygenation and the actual aquarium temperature.

Aim for slightly acidic to neutral water: pH 6.0–7.0 with roughly 5–12 dGH. If your tap water sits outside the preferred band, do not make abrupt chemical changes. Read the aquarium water chemistry guide, measure GH and KH as well as pH, and use a stable, repeatable preparation method.

Water quality must remain consistent. Ammonia and nitrite should be undetectable, nitrate should be controlled, and replacement water should be dechlorinated and matched closely for temperature. Small regular water changes are safer than infrequent large corrections. Never add pH-lowering chemicals simply to reach a published number; changing pH without understanding hardness and buffering can create dangerous swings.

Use a mature sponge filter, a gently directed internal filter or another system that provides dependable biological filtration without turning the surface into a fast current. Some surface movement is useful for gas exchange, but leave calm feeding and resting zones. If every floating plant is being pushed to one corner and the fish must swim continuously to hold position, the flow is too strong for the intended layout.

Warm water holds less oxygen than cool water. Watch more carefully during hot weather, after medication and if a power cut stops filtration. Rapid breathing, persistent gathering at one small area or unusual inactivity needs investigation. Check temperature, oxygenation, ammonia and nitrite before guessing at a disease.

Plants, substrate, lighting and cover

Floating plants are among the most useful parts of the setup. Salvinia, Amazon frogbit, water sprite or other suitable floating growth can diffuse light, create shaded stations and support tiny organisms that fry may graze. Leave some open feeding lanes and prevent plants from sealing the entire surface. Fine-leaved plants or spawning mops are useful when breeding is intended.

A dark sand or fine gravel substrate reduces glare and suits the subdued appearance of a coastal forest aquarium. Pale reflective substrate can make shy killifish feel exposed. Add smooth wood, roots and leaf litter if they can be maintained safely; these features provide visual breaks and a natural setting, but they must not trap large amounts of uneaten food.

Leaf litter and aquarium-safe wood may release tannins and give the water an amber tint. The colour itself is not a reason for a sudden water change, but botanicals can influence acidity and must be introduced gradually while pH and KH are monitored. Use only materials sold for aquarium use or collected from a reliably clean, pesticide-free source and correctly prepared. Replace decaying material in stages rather than stripping every leaf at once, because the shaded surface structure and established microbial community are part of the habitat the fish uses.

Moderate lighting is enough for the fish. Choose plant species that tolerate the shaded surface and adjust intensity or duration for healthy plant growth without flooding the aquarium with glare. A consistent day-night cycle is preferable to abrupt or prolonged illumination. Switch room and aquarium lights in a way that does not suddenly startle fish into the cover.

Do not rely on caves as the main shelter. Spotted Panchax uses the upper water, so cover should reach the surface. Tall stems, floating leaves and fine branches are more useful than a pile of deep rock caves. Keep enough open surface for feeding, inspection and gas exchange.

Feeding Spotted Panchax well

The mouth position and hunting behaviour show that this is a surface feeder. Offer small floating or slowly sinking foods that remain available in the upper water. A quality small flake, micro-granule or appropriately sized soft pellet can provide a dependable prepared base when the fish accepts it. Rotate this with frozen or live daphnia, cyclops, Artemia, mosquito larvae and other safe, correctly sized aquatic invertebrate foods.

Variety supports body condition and natural feeding behaviour. Live and frozen foods are particularly useful when conditioning adults for breeding, but they should come from a trusted source. Avoid wild-collected foods from water that may contain fish parasites, pesticides or pollutants. Do not feed live vertebrate prey.

Feed small observed portions once or twice daily. Food should be eaten promptly; material that drops behind plants or sits on the substrate does not help a surface feeder and can degrade water quality. If faster tank mates take every item, feed across several surface stations or use a feeding ring near the Panchax cover. Watch each fish rather than assuming that food placed in the aquarium reached the whole group.

Food type	Use	What to watch
Small floating flake or micro-granule	Prepared dietary base where accepted	Use a size the fish can swallow; discard stale food
Frozen daphnia, cyclops or baby brine shrimp	Variety and conditioning	Thaw appropriately and avoid leaving excess among floating roots
Live daphnia, Artemia or cultured small invertebrates	Natural hunting behaviour	Use clean cultures from a trusted source
Very fast-sinking foods	Usually poor as the only option	Much of the food may leave the fish's feeding zone

Tank mates and compatibility

Spotted Panchax can work in a carefully planned peaceful community, but the word peaceful does not mean harmless to anything smaller. It is a small predator. Tiny fish, newly born fry and very small shrimp may be eaten. The best companions are calm, similarly sized fish that use the middle or lower water, accept the same soft to moderately soft conditions and do not monopolise food.

Avoid aggressive surface fish, persistent fin-nippers, very boisterous feeders and fish large enough to swallow a Panchax. Also avoid mixing species only because both are called killifish. Killifish vary widely in adult size, aggression, water requirements and life history. Compare every candidate at adult size and use the tank mate checker as a starting point, followed by species-specific research.

Compatibility also depends on the layout. Provide several upper-level refuges and a separate feeding route for the Panchax. Watch for quiet exclusion: a subordinate fish may lose weight or remain hidden without showing torn fins. Persistent chasing, clamped fins, refusal of food, surface pinning or a hollow belly requires prompt action.

Companion type	Assessment	Reason
Peaceful, similarly sized midwater or bottom fish	Often suitable after water and adult-size checks	Less competition for the surface zone
Tiny nano fish, newborn fry or shrimplets	Avoid where survival matters	They may be treated as prey
Fast, boisterous surface feeders	Usually unsuitable	They can cause stress and take every meal
Large or aggressive predators	Avoid	Injury or predation risk
Other male Panchax in a proper group	Possible with enough room and cover	Display and chasing need dispersed territories

For other upper-water fish sold by Tropical Fish Co, compare the active Lampeye listing. It is a comparison link, not an automatic tank-mate recommendation. If you are considering a larger and more predatory panchax, read the Gold Striped Panchax listing and plan the species separately.

Sexing, group composition and breeding

Mature males are generally more colourful and may show longer fin extensions; females tend to be plainer and fuller-bodied. These differences are not reliable enough to promise sex for small dispatch-size fish. One quantity remains one unsexed fish. Ordering several fish does not guarantee a particular male-to-female ratio.

Epiplatys dageti is an egg-laying, non-annual killifish, not a livebearer. Adults scatter adhesive eggs among fine plants or spawning mops. Specialist sources report that breeding can occur readily in good conditions, but adults may eat eggs and fry. A separate breeding aquarium or the regular removal of egg-filled mops improves control and survival.

A breeding setup can use mature water, an air-driven sponge filter, fine-leaved plants or mops and subdued light. Condition adults with varied high-quality foods. A temporary breeding tank is for a managed breeding period; it is not evidence that a small bare aquarium is suitable for permanent group maintenance.

Eggs are normally water-incubated rather than stored dry. Specialist killifish references report hatching after roughly 10–14 days around 21–23°C, although development varies with temperature and conditions. Inspect eggs without allowing them to dry, remove fungused eggs carefully, and avoid routine medication unless a real problem has been diagnosed.

Newly hatched fry are tiny and need very small live food such as infusoria or rotifers before moving to vinegar eels and freshly hatched Artemia as they grow. Fry feed near the surface, so floating cover and clean, gently filtered water remain important. Use small frequent maintenance rather than large sudden changes. Separate larger juveniles if size differences create predation.

Health, quarantine and warning signs

A healthy Spotted Panchax should hold a level position near the surface, show clear eyes and intact fins, breathe steadily and respond to food. Colour alone is not a health test because stress, age, sex and lighting can change appearance. Look at body condition, posture, respiration and behaviour together.

Quarantine new fish when possible. A separate mature observation aquarium lets you confirm feeding, watch for parasites and avoid exposing an established display. Use dedicated nets and siphons or disinfect equipment correctly between systems. Quarantine is particularly valuable when combining livestock from different suppliers.

Common warning signs include repeated gasping, clamped fins, spots, cloudy patches, frayed fins, weight loss, rubbing, isolation and refusal of food. Jump injuries can affect the mouth or head. Test water first because ammonia, nitrite, low oxygen and sudden parameter changes can mimic disease. Do not raise temperature or add medication without matching the treatment to a credible diagnosis.

Follow medication labels exactly and account for sensitive invertebrates and plants. A hospital aquarium is often safer than medicating an entire community. Copper-based treatments can be dangerous to shrimp and snails. Continue strong aeration where the medicine permits it, because some treatments and warmer water reduce available oxygen.

Routine maintenance for a stable Panchax aquarium

A simple repeatable routine is more useful than trying to make the aquarium look untouched. Check the fish at feeding time every day: count visible individuals, confirm that each fish reaches food, watch the breathing rate and look for one animal being excluded from the best cover. Check the lid after feeding and after any work in the tank. A cable moved only a few millimetres can reopen an escape route.

Test ammonia and nitrite whenever behaviour changes, after a filter interruption, after adding livestock or when the aquarium is still maturing. In an established system, track nitrate, pH, GH and KH often enough to understand the normal pattern rather than testing only after a problem. Record the results. A written trend makes a gradual loss of buffering or rising nitrate much easier to identify than a single isolated reading.

Use regular partial water changes appropriate to the stocking level and test results. Prepare replacement water with a conditioner that treats the disinfectant used by your water supplier, and match the aquarium temperature closely. Clean accessible waste from quiet areas without stripping every surface at once. Rinse biological filter media only as the manufacturer directs, normally in removed aquarium water or prepared dechlorinated water, so the bacterial colony is not exposed to untreated tap water.

Trim floating plants before they form a sealed mat. Keep shaded refuges, but preserve open surface lanes for feeding, inspection and gas exchange. Remove dead leaves before they decay heavily, and check that roots are not trapping old frozen food. When pruning or moving equipment, count the fish before lifting the lid and again after closing it.

Filter maintenance should preserve both biological capacity and gentle flow. A clogged sponge can reduce oxygen and circulation, while an overpowered replacement can remove every calm surface zone. After cleaning, confirm that the filter restarted, the heater is operating normally and the lid fits around the equipment. Never leave a filter switched off with stagnant media for a long period and then restart it into the aquarium without assessing the risk.

During hot weather, measure the actual water temperature rather than relying on the heater setting. Increase safe surface agitation, keep filters running and avoid unnecessary heavy feeding if oxygen is becoming limited. Do not add ice directly or make a sudden large temperature correction. If cooling equipment is needed, introduce the change gradually and make sure the cover remains secure.

Observation	First checks	Immediate response
Fish gathering at one corner or breathing rapidly	Temperature, oxygenation, ammonia, nitrite and flow	Improve safe aeration and correct measured water problems gradually
One fish stays hidden and misses food	Chasing, cover distribution, group size and feeding competition	Add visual breaks, spread feeding stations and prepare separation if pressure continues
Food remains below the surface	Food size, buoyancy, portion and tank-mate speed	Use smaller surface foods and remove accessible leftovers
Fish repeatedly tests the lid	Open gaps, aggression, sudden light, water quality and disturbance	Close every gap and identify the underlying stressor
pH changes between water changes	KH, source-water values, organic load and preparation method	Stop chasing pH alone; investigate buffering and make changes slowly

Arrival and acclimation

Prepare the covered, cycled aquarium before dispatch. On delivery, inspect the unopened bag promptly and follow the current Live Arrival Guarantee and delivery instructions before opening or discarding any packaging. The guarantee is governed by the current policy on that page; this description does not promise a particular delivery day or courier timetable.

Keep aquarium lighting low while the fish settles. Match temperature and water chemistry gradually using the acclimation method appropriate to the shipment, then transfer the fish without adding transport water to the display. Avoid feeding heavily immediately. Observe breathing, posture and the ability to hold position in the chosen flow.

New fish may remain beneath floating cover at first. Provide quiet, do not chase them into the open for photographs, and check that every individual begins feeding. If the aquarium already contains fast feeders, offer food at several surface stations. Record any continuing refusal of food, loss of balance or injury and seek experienced aquatic-veterinary or specialist advice when needed.

Spotted Panchax compared with similar choices

Spotted Panchax is a useful choice for a keeper who wants a small upper-water fish with visible social behaviour and is prepared to build the aquarium around a group and secure lid. It is not the best choice for a tiny uncovered nano tank, a hard alkaline livebearer setup or a shrimp-breeding aquarium where every shrimplet must survive.

Question	Spotted Panchax answer	Planning consequence
Is it a livebearer?	No, it is a non-annual egg scatterer	Use plants or mops and protect eggs or fry if breeding
Can one fish be kept alone?	A proper group is preferred	Plan for at least six rather than buying one as a solitary display
Does it suit hard alkaline water?	It is better suited to slightly acidic, soft to moderately soft water	Measure the source water and choose fish that genuinely suit it
Is it safe with fry and tiny shrimp?	No guarantee; both may be prey	Use separate breeding or shrimp systems where survival matters
Is it a bottom or midwater fish?	It lives mainly at the surface	Provide floating cover, calm upper water and surface food

For another small African killifish with different colour and care context, see the active Australe Lyretail Panchax listing. Compare the complete adult care plan rather than choosing only by colour. Similar common names do not make two fish interchangeable.

Designing the surface as usable habitat

Treat the waterline as a floor plan rather than leaving it as one open sheet. A successful layout gives the group at least three functions: shaded resting cover, an open feeding lane and a gently moving area for gas exchange. These zones can overlap, but none should occupy the whole surface. The fish should be able to leave the filter current, feed without entering another male's preferred station and move between plant cover without being trapped in a dead corner.

Arrange floating plants in several islands instead of one solid mat. Long roots provide useful visual breaks, while small open gaps let you inspect the fish from above and place food where every individual has a chance to feed. Direct the filter return along an edge or against glass rather than through every refuge. Fine branches or tall stems can connect lower structure to the surface, but leave a clear route for maintenance and make sure no decoration creates a gap in the lid.

Recheck the surface after each major plant trim, filter clean or equipment change. A layout that worked last month can become exposed when floating roots are removed or too turbulent when a cleaned filter regains its full flow. Observe the whole group at feeding time: note whether fish can hold position without constant effort, whether one individual controls every calm station and whether food reaches more than one part of the aquarium. Adjust plant islands, flow direction and feeding points gradually, then watch the response before making another change.

Why buy this fish from Tropical Fish Co?

Use the live selector above for current stock, price and size availability. Each quantity is one unsexed fish in the selected dispatch size. Sex, pairing, exact adult colour and a named collection locality are not promised, so the aquarium should be planned for the species and social group before ordering.

Eligible livestock orders are covered by the current Live Arrival Guarantee. Fish are packed for specialist UK livestock transport, and the policy page explains the evidence and contact steps to follow if there is a problem. Read the delivery information before ordering and make sure someone can inspect the shipment promptly.

Before adding Spotted Panchax to the basket, confirm that the aquarium is mature, securely covered and suitable for a group of at least six. Check the selected dispatch size, measure the water and consider every existing tank mate at adult size. Those checks do more for a successful purchase than any claim that the fish is universally easy or suitable for every community.
