Overview

The African Butterfly Fish (Pantodon buchholzi) is a truly unique freshwater species that traces its lineage back millions of years. Belonging to the order Osteoglossiformes, it is a distant relative of the mighty Arowana. Known for its remarkable ability to leap from the water and glide short distances to catch prey or escape predators, this fish is a captivating addition to a specialized aquarium.

Distribution and Habitat

Native to the slow-moving and stagnant waters of West Africa, primarily within the Congo and Niger River basins, they inhabit swamps, creeks, and heavily vegetated pools. They spend their entire lives at the water's surface, utilizing the dense canopy of floating plants for camouflage and ambush hunting.

Description of African Butterfly Fish

Body shape:

They possess a highly specialized, boat-like body that is flattened on the dorsal (top) side, perfectly adapted for a life spent entirely at the water's surface.

Color:

Their coloration is a highly effective camouflage, featuring mottled patterns of brown, tan, and black that perfectly mimic a dead leaf floating on the water.

Barbels:

While they lack true barbels, their pelvic fins feature highly elongated, trailing rays that hang down into the water column, acting as sensory organs to detect vibrations from below.

Snout:

They have a large, highly upturned (superior) mouth designed explicitly for engulfing insects and small fish at or just above the water's surface.

Eyes:

Their large eyes are positioned high on the head, allowing them to simultaneously scan the surface for fallen insects and watch for aerial predators.

Fins:

The most striking feature is their massive, wing-like pectoral fins. When viewed from above, these fins give the fish a distinct butterfly appearance and aid in their leaping abilities.

The Tail:

The caudal fin is pointed and features elongated central rays, contributing to their ragged, leaf-like silhouette.

Temper

Semi-aggressive. While they are generally peaceful toward fish that inhabit the middle and lower levels of the aquarium, they are opportunistic predators. Any fish small enough to fit into their surprisingly large mouths that ventures near the surface will be considered food.

Sociality

They can be kept singly or in small groups. If kept in a group, a large surface area is required, as they can be somewhat territorial towards their own kind at the surface.

Activity

They are primarily nocturnal and crepuscular hunters. During the day, they will often remain completely motionless among floating plants, waiting for dusk to become more active.

Keeping and Caring for African Butterfly Fish

Tank size:

A minimum of 30 to 40 gallons is recommended. Because they exclusively inhabit the top layer of the water, the tank's footprint (length and width) is far more important than its depth. A tight-fitting, heavy lid is absolutely mandatory, as they are prolific jumpers.

Water Parameters:

Temperature

Maintain a warm environment between 23-30°C (73-86°F).

pH

They prefer slightly acidic to neutral water, with a pH ranging from 6.5 to 7.5.

Hardness

Keep the water soft to moderately hard, ideally between 5-15 dGH.

Ammonia, Nitrite, Nitrate

Ammonia and Nitrite must be strictly 0 ppm. Nitrate should be kept below 20 ppm through regular water changes and good filtration.

Lighting

They prefer dim or subdued lighting. Bright lights can cause stress, making floating plants essential to diffuse the light.

Water flow

Very gentle to still. They are adapted to stagnant waters and will struggle against strong currents.

Decorations and Plants

Floating plants like Water Lettuce, Salvinia, or Frogbit are crucial. They provide necessary cover, reduce stress, and anchor the fish in place. Substrate and lower decorations matter little to this species, though driftwood can be used to release beneficial tannins.

Diet

They are strict surface-feeding carnivores. In the wild, their diet consists primarily of terrestrial insects that fall onto the water. In the aquarium, they should be fed a varied diet of crickets, fruit flies, bloodworms, and high-quality floating carnivore pellets.

Some Feeding Tips

They will almost never dive to chase sinking food. Ensure all food floats. Live insects offer excellent enrichment and trigger their natural hunting instincts.

Breeding

Breeding in captivity is difficult but possible. They are egg-scatterers that spawn at the surface. The eggs float and must be removed quickly, or the parents will consume them. The fry are exceptionally small and require tiny live foods like springtails or freshly hatched baby brine shrimp, fed exclusively at the surface.

Conclusion

The African Butterfly Fish is an extraordinary oddball that brings a piece of prehistoric evolution into the home aquarium. While they require specific care, particularly regarding their diet and a secure lid, their fascinating behaviors and unique morphology make them a highly rewarding species for dedicated aquarists.
