Clown Knifefish Tropical Fish Learn all about the Clown Knifefish's feeding habits and food types, its behaviour, its origins, its natural habitats, is it male or female, breeding advice and information, suitable tank mates, its sizing and growth range, minimum tank size, water PH and more. Use our fish community creator tool to plan your tank set up and ensure that the Clown Knifefish is the right fish for your aquarium.

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.
