Upside-Down Catfish Tropical Fish Learn all about the Upside-Down Catfish'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 Upside-Down Catfish is the right fish for your aquarium.

The Upside-Down Catfish is an extraordinary fish due to its unusual habit of spending most of its time swimming or resting upside down. The habit comes from its surface feeding nature in the wild, where it browses the underside of leaves and the waters surface for mosquito larvae and other creatures. These catfish are peaceful and can be kept either singly on in groups in a community aquarium. Provide plenty of hiding spots and large leaved plants under which the catfish can browse. A varied diet will maintain good health.
