Sexing

Males are more slender than females and have serrations towards the end of the pectoral spine, females do not have serrations.

Origin

Found in Europe and Asia, has been introduced in many countries and considered an invasive species.

Tank compatibility

Mainly a substrate fish, it will also move around the upper water columns, mainly in search of food. Only keep with fish that will not fit into its mouth.

Diet

Naturally, it feeds on fish, large invertebrates and small waterfowl. In the aquarium, it is likely that almost any foods offered will be eaten, and so with this, provide a variety in diet. Meaty foods should be given to this fish every so often.

Feeding regime

A large feeding every 3 or 4 days, more often when young.

Environment Specifics

Needs as much room as possible, so decorations may be out of the question. Provide good aeration and excellent filtration, as these are somewhat messy fish and water quality may deteriorate quickly.
Due to their size they are best kept only in very large aquaria, ponds or public aquariums. They are not suited to an average home aquarium. If kept in outdoor ponds local Environmental Agencies may need to be checked as this fish can thrive in temperate conditions and is already considered an invasive species in several countries.

Behaviour

Mainly predatory. Remains, for the most part, calm in aquariums, and is fairly inactive.

Identification

A large, brown catfish, differing from most other catfish by having a long, eel-like tail.
