African Butterfly Fish

Few fish have a backstory like this one. Pantodon buchholzi has remained essentially unchanged for over 100 million years, a genuine living fossil found in the slow, heavily vegetated rivers and swamps of West and Central Africa.

Flat-bellied and wide-finned, it drifts just under the surface like a leaf, those enormous pectoral fins fanned out like wings, waiting for something to make a mistake. The fins aren't just for show either. Butterfly fish can make short gliding leaps out of the water to catch prey or escape danger, which is exactly why a sealed lid isn't optional.

Water conditions should mimic the blackwater or clearwater environments it comes from: soft, slightly acidic, and warm, somewhere in the 25 to 28 degree range is a sweet spot. Hard alkaline tap water causes long-term stress and shortens lifespan noticeably. Filtration should be gentle since strong surface agitation disrupts the calm surface layer it depends on for hunting. Floating plants like Amazon frogbit or water lettuce make it feel secure and replicate its natural habitat well.

Feeding is where many keepers struggle early on. These fish are ambush predators hardwired to respond to movement at the surface. Floating pellets often get ignored entirely at first. Live or frozen insects, crickets, mealworms, waxworms, freeze-dried flies, and even live feeder guppies get results much faster. With patience, some individuals can be weaned onto high-quality floating sticks or freeze-dried foods, but it takes time. Skipping that acclimation period is a common frustration point for newcomers to the species.
