The Clown Knifefish is a beautiful fish, but reaches up to 100cm in the wild, and usually at least 50cm in aquariums, so only very large tanks (250cm/8 foot absolute minimum) are suitable. Plenty of hiding spots amongst decor and plants should be provided, along with open swimming spaces. Cover from bright light is also important. The Clown knife fish is intolerant of its own kind, so must be kept singly. Being a natural predator, tankmates must be a good size, peaceful, and robust.

This fish is excluded from the Compatibility Checker as it is unsuitable for community aquariums or may require expert care.
