- Found in Europe and Asia, has been introduced in many countries and considered an invasive species.
- 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.
- 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.
- A large feeding every 3 or 4 days, more often when young.
- 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.
- Mainly predatory. Remains, for the most part, calm in aquariums, and is fairly inactive.
- A large, brown catfish, differing from most other catfish by having a long, eel-like tail.
- One of the largest-living catfish species, the Wels Catfish has been recorded at a 5 metre length, although this record is doubtful and sightings today of fish this size are rare.
- In order to own this fish in the England or Wales a licence is required under the Prohibition of Keeping or Release of Live Fish (Specified Species) Order 1998.
