Spotted / Red-Chinned Panchax (Epiplatys dageti) – 3–5cm Sizes

Recognise the fish and its care priorities

Spotted / Red-Chinned Panchax is the common-name pairing used here for Epiplatys dageti. FishBase identifies Epiplatys dageti as the Redchin panchax, a freshwater African rivuline in the family Nothobranchiidae. It records the fish from around Monrovia in Liberia, through southern Côte d’Ivoire and into south-western Ghana. This fish suits a keeper ready to manage a covered, biologically filtered aquarium, maintain measured water conditions and plan for a small social group. FishBase also describes it as benthopelagic, so provide usable cover and swimming space throughout the aquarium.

The wider Epiplatys genus consists of African rivulines in Nothobranchiidae. That genus background establishes its African killifish context without assigning the habits of every other Epiplatys species to this fish. Similar common names are therefore a reason to check the scientific name rather than treating different panchax as interchangeable.

Choose it for a prepared aquarium

OATA describes killifish generally as small and peaceful, but also notes that they may be unsettled by boisterous companions. The decisive choices are the quality of the filter, the security of the cover, the number of fish planned and the behaviour of every intended tank mate.

FishBase records a maximum of 6 cm total length for male or unsexed fish. Treat that as the maximum recorded planning reference rather than the size every individual is guaranteed to attain. The 3–4 cm and 4–5 cm labels describe dispatch sizes, so leave room for growth and assess companions using the 6 cm reference.

Keep the aquarium plan centred on those practical needs. Colour, pictured markings and dispatch size should never be used to infer sex, temperament or eventual appearance. For other animals in the same broad retail group, browse the current killifish collection and compare each scientific identity and complete care plan separately.

Choose the dispatch size and plan for adulthood

One purchase supplies one animal. Use the live size selector to choose approximately 3–4 cm or 4–5 cm at dispatch. The size you select is the size supplied, not the adult size. Both sizes represent the same species and should be housed around the same maximum recorded adult-length reference of 6 cm total length.

Sex is guaranteed only when the selected option explicitly states male or female. This Spotted / Red-Chinned Panchax listing has no sex-guaranteed option. Order quantity therefore controls the number of fish, but it does not create a guaranteed male-to-female composition.

The gallery images are representative, based on reference photographs of this species, so colours can look slightly different from the live animal. Use the size selector for dispatch size and the written identity for species choice; do not use an image to decide sex or exact future colour.

Use the overlap between identity and aquarium guidance

OATA’s killifish guidance gives 22–27°C, pH 6.0–7.5, 4–12°dH, at least three fish and an aquarium of at least 40 litres for a small group of the smallest killifish. These are group-level figures. FishBase records Epiplatys dageti in environmental conditions of 21–23°C, pH 6.0–7.0 and 5–12 dH. A practical aquarium target within both sets of values is therefore 22–23°C, pH 6.0–7.0 and 5–12°dH.

Begin with at least 40 litres as a baseline, then choose more space when the aquarium will contain additional fish or needs more planted refuges. Volume alone does not make a setup suitable: the filter must be established, the cover must fit securely, and measured water values must fall within the plan before the group is introduced.

Match and stabilise the water before adding fish

Set the aquarium to 22–23°C, pH 6.0–7.0 and 5–12°dH for a practical overlap between the species’ recorded environmental values and OATA’s aquarium guidance for killifish. Measure the aquarium rather than relying on a heater dial or a general description of local tap water. Temperature, pH and hardness answer different questions, and a suitable reading in one column does not cancel an unsuitable result in another.

Test the values that affect immediate welfare

• Ammonia: keep at zero milligrams per litre.
• Nitrite: keep at zero milligrams per litre.
• Nitrate: keep it from exceeding the normal tap-water level by more than 20 milligrams per litre.
• General hardness: use 5–12°dH as the planning overlap for this fish.
• Carbonate hardness: OATA gives 3–10°dKH for killifish generally; monitor it alongside pH because it helps you understand how stable the pH is likely to remain.

Use the aquarium water chemistry guide to distinguish pH, GH, KH, ammonia, nitrite and nitrate before changing anything. After measuring the values, use the water matcher to compare the aquarium with the stated planning range.

Respond to a result in the right order

If ammonia or nitrite is above zero, pause new additions and deal with the biological-filtration problem. Test again after corrective maintenance rather than assuming a water change has settled it. When nitrate rises, compare it with the tap-water baseline and review feeding, stocking and the weekly maintenance routine.

If pH, GH or temperature lies outside the plan, avoid a sudden correction. First test the replacement water, confirm the result with a suitable aquarium test and decide whether a repeatable preparation method can hold the desired value. Stability comes from understanding the starting water and using the same controlled process at each change.

Build a covered, planted home with enough capacity

Use an aquarium of at least 40 litres as OATA’s baseline for a small group of the smallest killifish, then increase the volume according to the complete stocking plan. FishBase’s 6 cm maximum for Epiplatys dageti provides the adult-size reference, while the OATA figure supplies the aquarium baseline. More water gives the filter and keeper a larger buffer against rapid changes, but it does not replace regular tests or maintenance.

A cover is essential for killifish. Fit it before the fish arrive and return it securely after feeding, testing or maintenance. Check the areas around filter fittings and other equipment whenever anything is moved. Plants may make a group feel less exposed, but planted cover and a physical aquarium cover perform different jobs.

Give each part of the setup a clear purpose

OATA recommends a heavily planted aquarium and specifically connects cover with keeping multiple males together. Use live planting where practical. If live plants are not part of the setup, add aquarium-safe artificial plants and suitable ornaments so fish can move away from one another rather than remaining continuously exposed.

Prepare and mature the filter before livestock arrives. The first tropical aquarium guide explains how to establish the system before fish are introduced. A newly filled aquarium is not ready merely because its temperature has reached the target; the biological filter must be able to process waste while ammonia and nitrite remain at zero.

Make the final pre-arrival check

1. Confirm that the aquarium holds at least 40 litres before any allowance for other livestock.
2. Fit the cover and close openings around equipment.
3. Confirm that the filter is running and has been matured.
4. Test ammonia and nitrite and require zero milligrams per litre for both.
5. Measure 22–23°C, pH 6.0–7.0 and 5–12°dH.
6. Place plants or alternative cover before introducing the fish.

Plan the group without assuming sex

OATA advises keeping at least three killifish for companionship. Its broader composition guidance is two females to each male, intended to reduce pressure on females and other inhabitants. The retail size choice controls size rather than sex, so build enough aquarium capacity for a group without treating an order of three as a guaranteed ratio.

Add up the complete adult stocking plan before deciding quantity. One purchase supplies one animal, meaning a planned group of three requires three purchase units. If other fish already occupy the aquarium, include their adult sizes and waste load when deciding whether the 40-litre baseline remains adequate. Increase the aquarium size rather than compressing a mixed community into the minimum figure.

Separate quantity from composition

Plants and ornaments help distribute shelter when several fish share the aquarium. Arrange more than one covered area so an individual can move away from another fish. During feeding, watch whether each animal can leave cover and obtain food. A fish that repeatedly misses meals or remains concealed needs attention even when there is no obvious fin damage.

Increase numbers gradually rather than adding the entire intended community in rapid succession. OATA explains that the beneficial bacteria in a mature filter must increase as fish numbers and feeding rise. Stocking too quickly can leave the bacterial population unable to process the additional waste, causing ammonia or nitrite to rise.

Use tests to decide whether the filter has handled each addition. Ammonia and nitrite must remain at zero, while nitrate should stay within the stated limit above the tap-water baseline. If either toxic compound appears, pause further additions and correct the water-quality problem. Add further livestock only after the aquarium is stable again.

Review the plan at three moments

• Before ordering: calculate quantity, adult size and total aquarium stocking.
• Before introduction: confirm zero ammonia and nitrite and check that cover is distributed around the aquarium.
• After introduction: watch access to food, hiding and interactions before adding more livestock.

Feed once a day and watch every fish eat

OATA describes killifish as omnivorous and recommends a good-quality flake or granule as the regular aquarium food. It also advises small live or frozen items such as daphnia, brine shrimp or tubifex. Use food that is appropriately sized for the fish in front of you, particularly when feeding fish dispatched at 3–4 cm or 4–5 cm.

Feed once a day and offer only what the fish can consume within a few minutes. That time limit is a practical portion control: uneaten food breaks down and adds waste to the aquarium. More food is not a substitute for observing whether each member of the group actually reaches the meal.

Build a simple feeding decision

Watch the whole group during the few-minute feeding window. If one fish receives most of the food, distribute small portions to more than one place rather than increasing the total indiscriminately. If food remains after the group stops feeding, remove accessible leftovers and reduce the next portion.

Use feeding response as a daily health observation. OATA lists reduced intake or loss of interest in food among the changes that can signal a problem. Compare the individual with its usual behaviour: a sudden refusal matters more than whether it takes exactly the same number of flakes as another fish.

When feeding changes, check cause before quantity

• If every fish loses interest, test ammonia, nitrite and temperature promptly.
• If one fish misses food, watch for hiding, chasing or faster companions controlling the meal.
• If food remains uneaten, reduce the next portion and remove waste you can reach.
• If body condition changes, review how much each individual consumes rather than relying on the amount added to the aquarium.

Keep the schedule consistent enough to make changes easy to spot. A once-daily observed meal provides food while limiting the accumulation of uneaten material. Weekly water testing then shows whether feeding and stocking remain within the filter’s capacity.

Protect the biological filter during weekly maintenance

The RSPCA explains why biological filtration is vital: fish release toxic ammonia, established bacteria convert it to toxic nitrite and further bacteria convert nitrite to the safer nitrate. A working filter must therefore be set up before fish arrive and maintained without destroying the bacterial population that processes waste.

Follow OATA’s recommendation for a 25% partial water change at least once a week. Use a siphon to remove solid waste from the gravel or sand where needed. Treat replacement tap water with a conditioner that removes chlorine or chloramine before it enters the aquarium.

Use one repeatable weekly routine

1. Observe behaviour, breathing, appearance and feeding before disturbing the aquarium.
2. Test ammonia and nitrite; both should read zero milligrams per litre.
3. Check nitrate against the normal tap-water result and keep the increase within 20 milligrams per litre.
4. Remove 25% of the aquarium water.
5. Siphon accessible solid waste from the substrate.
6. Condition replacement water before adding it.
7. Check the filter for blockages and confirm that it restarts correctly.
8. Refit the aquarium cover securely around every item of equipment.

If filter media needs cleaning, rinse it lightly in water removed during the partial change. Do not run it under the tap because chlorine or chloramine may kill beneficial bacteria. Clean only as much as needed to restore operation rather than trying to make every mature surface look unused.

Test at least weekly even when the fish appear settled. Regular results establish the aquarium’s normal pattern and may reveal a deteriorating condition before behaviour changes. Test promptly after a filter blockage, interruption, unusually heavy feeding or any sign of distress.

Introduce the fish in controlled stages

Prepare the aquarium before arranging the arrival of livestock. The filter should already be mature, the cover fitted, plants or alternative shelter positioned and the intended water values stable. Test immediately before introduction and require ammonia and nitrite to be zero milligrams per litre.

Read the current delivery and Live Arrival Guarantee policy before the order is dispatched.

Follow the arrival steps in order

1. Be present to receive the parcel and start filming before the sealed parcel is opened.
2. Record one continuous take showing the sealed parcel, the opening and the fish still inside the sealed bag.
3. Float the bag for 20–30 minutes before releasing the fish.
4. Never pour the bag water into the aquarium.

Use water quality to control the stocking pace

OATA advises increasing fish numbers slowly because every addition increases waste and feeding. The filter’s beneficial bacteria need time to increase with that new load. An aquarium that processed the waste from its previous inhabitants may still be overwhelmed when too many animals are added together.

Once the fish enter the aquarium, allow them to use the prepared cover and observe without repeatedly disturbing the layout. Check swimming behaviour, breathing, body condition and response to the next scheduled feed. Count how many animals eat rather than judging the group only by the most visible individual.

During the first week, compare behaviour from day to day. OATA highlights surface hanging, sitting on the bottom, erratic swimming, unusual hiding, changes in aggression, altered breathing and reduced feeding as signs requiring attention. Test water promptly when any of these appears.

A small ammonia or nitrite reading is not a reason to continue stocking and hope the filter catches up. Pause additions, reduce avoidable waste and restore safe water quality. Keep testing until both compounds remain at zero. Only then should the next stage of the stocking plan be considered.

First-month priorities

• Keep the once-daily feeding portion within what is eaten in a few minutes.
• Complete a 25% partial water change at least once a week.
• Test ammonia and nitrite at least weekly and whenever behaviour changes.
• Check the filter for blockages and preserve its bacterial media.
• Watch whether each member of the group has access to food and shelter.

Act on changes in health or behaviour

Use daily observation to learn the group’s normal swimming, colour, temperament, breathing, appearance, body condition and feeding response. OATA recommends watching all of these because a change can identify a developing problem before it becomes more serious.

Compare the fish with clear welfare indicators

Healthy fish should have clear, bright eyes, undamaged fins, intact scales and appropriate swimming behaviour. Look for ulcerations, bumps, white spots, fluffy growths, missing fins or scales, and any increase or decrease in body weight and condition. No single observation replaces a water test, so combine appearance with behaviour and measured water quality.

Start with ammonia and nitrite because even small amounts can stress killifish. Confirm that the filter is operating, inspect it for blockages and check when the last partial water change was completed. Correct measured husbandry problems while avoiding abrupt alterations to pH, hardness or temperature.

When one fish hides or misses food, watch the group long enough to distinguish a health change from social pressure. Redistribute plants or suitable ornaments if one area contains all the shelter. Spread the normal feeding portion between several positions if a companion controls access to food.

When several fish change at the same time, investigate shared conditions first: water quality, filter operation, recent stocking and feeding load all affect the entire aquarium. Record the readings and visible signs so that the pattern is clear. Contact us for health guidance when changes continue after immediate water-quality checks.

Continue the weekly baseline even when no problem is visible: a 25% partial water change at least once a week, regular tests, conditioned replacement water and careful filter maintenance. Consistency gives you a reliable normal condition against which sudden changes can be recognised.

Screen every tank mate before mixing species

OATA describes killifish generally as small and peaceful but says they do not appreciate boisterous tank mates. It also warns that some may be shy and prone to bullying, while some males may be aggressive towards long-finned species. Apply those cautions directly: avoid boisterous companions and avoid long-finned species.

A named universal tank-mate list would ignore differences between individual species and aquarium layouts. Screen each candidate for adult size, temperament, water requirements, social needs and feeding behaviour. For this fish, the water comparison should include 22–23°C, pH 6.0–7.0 and 5–12°dH, while the size comparison should use the maximum recorded 6 cm total length rather than the dispatch size.

Use a five-part compatibility screen

Reject a proposed companion when any essential requirement conflicts. Matching temperature alone is insufficient if the other fish needs harder water, behaves boisterously or prevents this group from feeding. Likewise, a similar adult length does not make two fish compatible when their social behaviour differs.

Layout changes can reduce pressure but cannot make a fundamentally unsuitable combination safe. Use plants and suitable ornaments to create shelter, then watch for increased hiding, reduced feeding, altered breathing, damaged fins or changes in aggression. Those signs mean the community plan needs reassessment rather than another decorative addition.

Other killifish require the same individual scrutiny. OATA describes the group as diverse, and one shared retail label does not establish identical behaviour or care. Compare scientific identities and adult requirements before combining them.

For a stocking and compatibility assessment, contact us with the aquarium volume, measured water values, current inhabitants and the number of Panchax planned. That information allows the whole community to be considered rather than approving a companion name in isolation.

Use behaviour to review the community after introduction

A compatibility decision continues after the fish enter the aquarium. OATA’s warning signs include altered aggression, increased hiding, unusual swimming, changed breathing, damaged fins, declining body condition and reduced feeding. Check those indicators daily while a new community settles.

Distinguish an acceptable start from a failing mix

Feeding provides a useful worked check. Offer the normal once-daily amount that can be eaten within a few minutes. If a faster fish takes everything while the Panchax remain hidden, adding more food may only increase waste. Spread the existing portion between more than one place and decide whether the community still allows all fish to feed appropriately.

Hiding also needs context. Plants and ornaments should provide shelter, but a fish forced to remain concealed and lose condition is not benefiting from the community. Observe which animal approaches when it tries to leave cover. Persistent pressure means the social combination, not merely the amount of decoration, needs to change.

Test water whenever behaviour changes because a community-wide water problem can resemble a compatibility failure. If ammonia or nitrite is above zero, pause all further stocking and correct filtration and maintenance first. If measured water is safe and one species consistently causes chasing, food exclusion or fin damage, prepare a separate suitable aquarium rather than waiting for the condition to worsen.

Recheck after every stocking change

• Compare the new total waste load with the filter’s established capacity.
• Confirm ammonia and nitrite remain at zero.
• Watch each animal eat, not just the group as a whole.
• Inspect fins, scales, body condition and breathing.
• Confirm the cover and shelter remain correctly positioned.

Do not add another species to distract from aggression or hiding. Additional stocking increases biological load and may intensify competition. Stabilise the present aquarium, identify the cause and make one controlled change at a time.

Answer common questions before choosing this fish

How big does Spotted / Red-Chinned Panchax get?

FishBase records a maximum length of 6 cm total length for Epiplatys dageti. Plan the aquarium and assess companions using that adult-size reference rather than the 3–4 cm or 4–5 cm dispatch size.

What size aquarium does Spotted / Red-Chinned Panchax need?

Use a covered, biologically filtered aquarium of at least 40 litres for a small group. That volume is OATA’s killifish baseline for a small group of the smallest species, so increase it for additional stocking.

How many Spotted / Red-Chinned Panchax should I keep together?

OATA’s killifish guidance advises at least three for companionship and suggests two females to each male. Sex is not guaranteed here, so plan adequate capacity without assuming that quantity will create that ratio.

Is this fish suitable for a beginner?

FishBase describes Epiplatys dageti as easy to maintain in an aquarium. The keeper must still provide a mature biological filter, a secure cover, measured water, at least three fish and a 25% water change at least once a week.

What does Spotted / Red-Chinned Panchax eat?

Feed good-quality flake or granules once daily, adding small live or frozen foods such as daphnia, brine shrimp or tubifex for variety. Give only what the fish can eat within a few minutes.

What temperature and pH does it need?

Keep it at 22–23°C, pH 6.0–7.0 and 5–12°dH, the overlap between FishBase’s environmental range for Epiplatys dageti and OATA’s aquarium guidance for killifish.

Is Spotted / Red-Chinned Panchax aggressive or likely to nip fins?

OATA describes killifish generally as peaceful but says some males may be aggressive towards long-finned species. Avoid long-finned species and watch the group for chasing, hiding, damaged fins or food exclusion.

Which animals can this fish live with?

Screen calm fish individually for compatible water, adult size, temperament and access to food. Avoid boisterous tank mates and long-finned species, and treat the outcome of any other combination as uncertain until behaviour is observed.

How does Spotted / Red-Chinned Panchax arrive alive in the UK?

Someone must be present to receive it. Film every delivery continuously from the sealed parcel as it is opened, with the fish still in the sealed bag; float the bag for 20–30 minutes before release and never pour the bag water into the aquarium.
