African Butterfly Fish

The African Butterfly Fish, scientifically known as Pantodon buchholzi, belongs to the Oddballs family group. Adults reach a maximum size of approximately 12 cm and have a depressed body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the surface zone of the aquarium and produces a medium level of biological waste.

To thrive, the African Butterfly Fish requires a freshwater only aquarium with a minimum volume of 80 litres and a tank length of at least 80 cm. Water temperature should be maintained between 24°C and 30°C, with a pH range of 6–7.5 and a general hardness of 1–10 dGH. A low water flow is preferred.

Due to its specialist needs, the African Butterfly Fish is best suited for fishkeepers who can provide a carefully planned setup. The African Butterfly Fish is typically available in one standard form.

When setting up an aquarium for the African Butterfly Fish, a low water flow best suits their natural preferences. Because this species occupies the surface zone, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline. Useful additions include floating plants to diffuse overhead light and create shaded areas. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.

Classified as semi-aggressive, the African Butterfly Fish is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the surface zone can help reduce competition and territorial overlap.

African Butterfly Fish is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially plants.

The most common mistake is buying African Butterfly Fish for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

The African Butterfly Fish is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and is primarily active at dusk and dawn, so offering food shortly after lights-off ensures it receives adequate nutrition.
