Flying Fish / Freshwater Butterfly Fish (Pantodon buchholzi) - UK

The Freshwater Butterflyfish, often searched as Flying Fish in the aquarium trade, is one of the most unusual surface predators you can keep in a home aquarium. Known scientifically as Pantodon buchholzi, this ancient-looking species glides just under the waterline with huge wing-like pectoral fins, giving it a look that instantly stands out from other freshwater fish UK hobbyists usually see. Native to slow-moving waters in West Africa, the African Butterflyfish reaches around 10-13 cm, can live 5-10 years, and suits aquarists looking for a unique aquarium fish UK keepers rarely forget. It is peaceful in temperament but definitely not a beginner’s impulse purchase, because a proper butterflyfish tank setup, secure lid, calm surface, and thoughtful feeding routine matter from day one.

If you have ever wondered what do flying fish eat, how to manage butterflyfish surface feeding, or whether this species works in a freshwater butterflyfish for community tank layout, this freshwater butterflyfish care guide answers those questions in detail. See our detailed photos showing the broad fins, upturned mouth, and camouflage pattern that make this a truly unique surface-dwelling fish UK aquarists love. For fishkeepers who want a striking top-dweller with real character, the Butterfly Fish offers a fascinating centrepiece without needing a giant predator aquarium.

Where Do Freshwater Butterflyfish Come From? Natural Habitat Explained

The natural Pantodon buchholzi habitat is found across parts of West and Central Africa, especially the Niger Delta and Congo basin. In the wild, these fish live in slow creeks, floodplain pools, swamps, and heavily vegetated margins where overhanging plants drop insects onto the water. If you are asking where do flying fish live, the answer depends on which fish you mean. True marine flying fish belong to groups like Exocoetidae, hirundichthys, and cypselurus, but the aquarium Flying Fish sold here is a freshwater species from shaded African waters.

This distinction matters because online searches often mix up aquarium butterflyfish with sea species, including terms like flying fish barbados, barbados flying fish, flying fish in barbados, and even restaurant-related searches such as flying fish restaurant. Those terms usually refer to edible marine species, local cuisine like cou-cou and flying fish or cou cou and flying fish, or coastal wildlife rather than Pantodon buchholzi. In the aquarium, however, you are keeping a stealth predator that spends most of its time just under floating cover, waiting for insects or small prey to land above it.

Wild water is usually soft to moderately hard, warm, tannin-stained, and low in current. The fish relies on camouflage from above, so dappled light and floating vegetation are important. This is why an African butterflyfish for planted aquarium layout works so well when designed with open surface lanes and quiet corners. Re-creating these conditions reduces stress, improves appetite, and encourages more natural ambush behaviour.

Because this species is adapted to calm, shallow margins, it does poorly in bright, turbulent tanks with strong spray bars or aggressive surface agitation. Aquarists who succeed with this fish usually build around its top-dwelling lifestyle rather than treating it like a standard community species. That is one reason it remains one of the best surface-dwelling fish for aquarium displays where behaviour matters as much as colour.

How to Set Up the Perfect Tank for Freshwater Butterflyfish

A successful butterflyfish tank setup starts with understanding that this species lives almost entirely at the top of the aquarium. While the freshwater butterflyfish tank size minimum is 115 litres, a 200-litre aquarium is much better for long-term care, especially if you want tank mates. The extra footprint gives the fish more surface territory, which matters more than sheer depth. A longer tank is usually more useful than a tall one.

Tank Size Requirements

For a single specimen or a carefully chosen pair, 115 litres is the minimum. For a mixed display, 200 litres is the recommended size. This allows enough room for floating cover, feeding zones, and lower-level fish without crowding the surface. Since this species is a patient ambush hunter, it benefits from calm areas where it can remain still without being constantly disturbed by faster swimmers.

Water Parameters

The ideal African butterflyfish water parameters are stable rather than extreme. Keep the butterflyfish temperature between 23-30°C, with an ideal point around 26°C. The practical butterflyfish temperature range gives some flexibility, but sudden drops can suppress feeding. The freshwater butterflyfish pH range is 6.0-7.5, with around 6.8 being a very safe target. For hardness, Pantodon buchholzi water hardness of 2-15 dGH is suitable. These values make the species adaptable to many tropical freshwater systems in the UK as long as changes are gradual.

Filtration and Flow

Use efficient filtration, but avoid blasting the surface. A gentle external filter or well-baffled internal filter works well. This fish dislikes strong current because it naturally occupies still water. If the surface is choppy, feeding becomes less efficient and the fish may hide more. Calm water also helps with floating plants and surface insect feeding.

Substrate, Plants and Decor

Substrate is less important than the upper layout, but dark sand or fine gravel helps create a more secure look. Add wood branches, trailing roots, and broad-leaved plants below, while keeping the top partially shaded with floating plants. An African butterflyfish for planted aquarium design can include Salvinia, Amazon frogbit, or water lettuce if your lighting and lid allow it. Leave open feeding gaps so the fish can strike upward without obstruction.

For suitable companions in the lower levels, browse our Elephant Nose Knifefish, Elephantnose Fish, Protomyzon pachychilus, and X Rhombo Barb. In larger oddball displays, some keepers also explore species such as the Silver Arowana or Australian Bonytongue, though these require much more space and careful planning.

Lighting and Lid Requirements

Moderate lighting is ideal. Very bright tanks can make the fish feel exposed unless floating cover is dense. The most important hardware point is the butterflyfish tank lid requirement: this species is an excellent jumper. A tight-fitting hood with no gaps around cables or pipework is essential. Leave a little humid air space between the waterline and lid to protect the labyrinth-like surface-feeding routine and reduce injury if the fish jumps.

What Do Freshwater Butterflyfish Eat? Complete Feeding Guide

If you are searching what do flying fish eat, the answer for Pantodon buchholzi is simple: insects and other meaty foods taken from the surface. This is a classic butterflyfish insect eating fish, built for upward strikes. In the wild, it takes terrestrial insects, mosquito larvae, small crustaceans, and tiny fish. In captivity, successful freshwater butterflyfish feeding depends on offering floating or surface-presented foods that trigger the fish’s natural hunting response.

Staple Foods

The best staple diet includes floating carnivore pellets, insect-based sticks, and frozen foods presented near the surface. Many specimens accept floating pellets after settling, but newly imported fish often prefer live or frozen insects first. A balanced butterflyfish diet should focus on protein-rich foods rather than generic community flakes that sink too quickly.

Supplemental Foods

Good supplemental options include bloodworm, mosquito larvae, brine shrimp, chopped krill, and small crickets. Occasional live foods can be very useful for conditioning difficult feeders. Because this species is specialised for butterflyfish surface feeding, use feeding rings or target feeding if midwater fish steal food first.

Treats and Foods to Avoid

Treats can include waxworms or small locusts in moderation, but avoid fatty foods too often. Do not rely on feeder fish, as they can introduce parasites and encourage poor nutrition. Sinking foods are usually ignored. If you keep this fish with boisterous tank mates, watch carefully to make sure it is actually eating.

Adults do well on one to two small feeds daily. Juveniles may need smaller, more frequent meals. In mixed tanks, use a quiet corner so the fish can feed without competition. This is one reason it remains one of the best surface-dwelling tropical fish for keepers who enjoy species-specific feeding behaviour rather than frantic community feeding.

Freshwater Butterflyfish Appearance: Colors, Patterns & Varieties

The first thing most keepers notice is the dramatic fin shape. Pantodon buchholzi size typically reaches 10-13 cm, but the fish looks larger from above because of its broad pectoral fins. These fins spread like wings, which is why the species is often called the flying fish in freshwater circles even though it does not truly glide like marine species. The body is flattened from top to bottom, the mouth is strongly upturned, and the eyes are positioned for surface hunting.

Base colour is usually mottled brown, tan, silver, and olive, with darker marbling that helps the fish disappear among floating leaves. The ventral fins are elongated and can show subtle reddish or warm tones, which is why some hobbyists notice similarities to freshwater fish with red fins. This camouflage is much more important than bright colour. It is a predator designed to blend in, not to flash across the tank like schooling tetras.

Males and females can be sexed by the anal fin. Males usually develop a more notched anal fin, while females have a rounder shape. There are no widely established colour morphs in the trade, so quality is judged more by finnage, body condition, and alert posture than by unusual strain names. Our photos show the intense chocolate-brown patterning and broad fin spread that healthy specimens display when kept over dark substrate and under broken surface light.

Search terms like flying fish roe, flying fish beer, flying fish cove, flying fish cove christmas island, and cou-cou and flying fish refer to marine species or regional food culture, not this aquarium fish. That confusion is common, so it helps to remember that the aquarium Butterfly Fish is a freshwater ambush predator from Africa, not a sea fish from tropical coasts.

What Fish Can Live With Freshwater Butterflyfish? Compatibility Guide

Pantodon buchholzi tank mates need to respect one simple rule: leave the surface layer alone. This species is peaceful, but it is also a predator with a large mouth and a strong feeding response. Small fish that hover near the top may be eaten, while hyperactive fish that splash constantly can stress it. That is why freshwater butterflyfish for experienced keepers is a fair description; success depends on choosing tank mates by swimming level and behaviour, not just by water parameters.

Ideal Tank Mates

Good companions are calm midwater or bottom-dwelling fish that enjoy similar warm, slightly acidic to neutral water. Suitable examples include larger tetras, peaceful knifefish, Corydoras in the right temperature range, and some oddball species that occupy lower zones. Browse the Elephant Nose Knifefish for a classic lower-level oddball companion, or the Four-Spotted Copeina - Pyrrhulina Spilota - if you are planning a more specialised South American-style display with caution around surface use. In larger setups, the Australian Bonytongue and Silver Arowana are comparison species for advanced keepers, though they are not simple community partners and need much larger aquariums.

Species to Avoid

Avoid tiny rasboras, hatchetfish, guppies, and any fish that spends long periods at the top. Also avoid fin-nippers and very active splashing fish. Searches like freshwater butterflyfish vs hatchetfish come up often because both are surface fish, but they are generally poor companions in modest tanks due to competition for the same layer. Likewise, freshwater butterfly vs betta is not ideal because both may use the upper zone and both can become stressed by the other’s presence.

Community Tank Examples

In a 200-litre aquarium, one Butterfly Fish can work with a group of medium tetras and a peaceful bottom group. In a larger oddball setup, one specimen may be combined with a carefully selected knifefish and robust bottom dwellers. This is not the best choice for a busy all-levels community, but it can be excellent in a calm, structured display. That is why many hobbyists see it as a surface fish UK enthusiasts choose for a themed aquarium rather than a generic mixed tank.

Invertebrates

Large snails are usually ignored, but small shrimp may be taken if they reach the surface or if juveniles are present. Surface insects and anything wriggling near the top can trigger a feeding strike.

Searches such as African butterflyfish vs killifish and Pantodon buchholzi vs archerfish are useful comparisons. Killifish can share some surface habits, but many are smaller and more delicate. Archerfish are stronger, brackish-leaning shooters in many cases and not a direct substitute for a true freshwater surface ambush fish. If you want a calm top predator with ancient looks, Butterfly Fish is usually the better fit for tropical freshwater. If you want a more active display hunter, archerfish may suit a different setup entirely.

This species is among the more unique surface-dwelling fish UK aquarists can keep, but it is not a fish for random stocking. Think carefully about flying fish size, mouth width, and feeding style before adding anything small. Compared with popular fish in UK community tanks, this fish is more specialised, but that is exactly what makes it so rewarding.

How to Breed Freshwater Butterflyfish: Complete Breeding Guide

Freshwater butterflyfish breeding is possible, but it is considered difficult and is usually attempted by dedicated aquarists rather than casual keepers. This is a surface-spawning egg layer, and successful breeding depends on stable warm water, heavy conditioning with live foods, and a quiet setup where the fish feel secure. If you enjoy unusual projects and want to learn more than basic flying fish facts, this species offers a genuinely interesting challenge.

Breeding Setup

Use a separate breeding aquarium with calm water, floating plants, and a secure lid. Keep temperature near the upper end of the normal range, around 27-30°C, and maintain soft to moderately soft water. Condition the pair with insect-rich foods. Because the species is shy, visual barriers and subdued lighting help.

Spawning and Egg Care

Spawning usually occurs near the surface. Eggs are buoyant and float. Adults may eat eggs, so many breeders remove the parents or collect the eggs. Gentle aeration is enough; strong flow can scatter or damage eggs. Hatching time varies with temperature but is usually within a few days.

Fry Care

Fry need very small live foods at first, then larger prey as they grow. Surface access is important from the beginning. Growth can be uneven, so sorting by size may be necessary to reduce losses. This is one reason the species is not commonly mass-produced compared with easier tropical fish.

Searches like small river fish species, protected freshwater fish species UK, invasive fish species UK, common bream freshwater fish UK, and edible freshwater fish UK are unrelated to breeding this species, but they highlight how often freshwater topics get mixed together online. For aquarists, the key point is that Butterfly Fish breeding is a specialist project focused on surface eggs, live foods, and stable conditions rather than large-scale community spawning.

Freshwater Butterflyfish vs Similar Species: Which Should You Choose?

Comparison matters because many aquarists searching for Flying Fish are actually deciding between several unusual top-dwelling species. The Butterfly Fish is best for keepers who want a calm, stealthy, insect-hunting predator in a tropical freshwater tank. It is not the same as marine types of flying fish such as Exocoetus volitans, and it should not be confused with hatchetfish or archerfish just because all three use the surface.

Searches like freshwater butterflyfish vs hatchetfish, Pantodon buchholzi vs archerfish, and African butterflyfish vs killifish all reflect the same question: do you want a display fish, a shoaling fish, or a behaviour fish? Butterfly Fish is the behaviour fish. It is less about bright colour and more about posture, strike response, and that unforgettable surface silhouette. If you want something equally unusual, you may also enjoy browsing the Four-Spotted Copeina - Pyrrhulina Spilota - or the X Strawberry Rasbora for contrast in smaller displays.

Common Health Problems in Freshwater Butterflyfish & How to Prevent Them

A healthy Pantodon buchholzi rests just under the surface, reacts quickly to food, holds its fins open, and shows no fraying, cloudiness, or laboured breathing. Good Pantodon buchholzi behaviour includes calm hovering, sudden feeding strikes, and selective use of shaded areas. If the fish constantly hides, crashes into the lid, or refuses food for long periods, review water quality and tankmate pressure first.

Common Issues

The most common problems are jump injuries, starvation from poor feeding strategy, and stress caused by excessive flow or unsuitable companions. Standard tropical diseases such as ich, fin damage, and bacterial infections can occur, especially after transport or in uncycled tanks. Because this fish lives at the surface, oily films and poor oxygen exchange can also affect it more quickly than bottom dwellers.

Treatment and Prevention

Prevention is better than cure. Keep water stable, use a secure lid, and feed a varied insect-based diet. Quarantine all new fish. If treatment is needed, move the fish to a hospital tank when possible so you can medicate accurately. Avoid guessing with random products. Warm, calm tanks can deteriorate fast if overfed, so regular testing matters.

Searches like flying fish common name, flying fish attack, blue flying fish, and marine references such as california flying fish often appear online, but for aquarium health the important point is species identity. This is not a marine glider from the open sea. It is a warm-water freshwater predator whose health depends on calm surface conditions, secure housing, and proper insectivore nutrition.

Understanding Freshwater Butterflyfish Behavior in the Aquarium

Pantodon buchholzi behaviour is what makes this species so memorable. It is not a constant swimmer. Instead, it spends long periods motionless near the surface, using tiny fin adjustments to hold position. Then, in a split second, it lunges at prey. This patient hunting style is why many keepers become fascinated with it after the first week.

It is generally peaceful toward fish too large to swallow, but it is not social in the way schooling fish are. Most specimens are best kept singly unless the tank is large and carefully structured. They are most active during feeding time and in dimmer periods of the day. Floating plants, subdued light, and quiet tank mates bring out the most natural posture.

People sometimes search for unrelated phrases like flying fish swimming, flying fish video, flying fish game, flying fish ride, or even flying fish water sport when trying to understand how these fish move. In the aquarium, the real appeal is not gliding above water but the stealthy, almost prehistoric way this fish patrols the surface film.

Why Buy from Tropical Fish Co?
