Black Devil Catfish/Crystal Eyed Catfish-Hemibagrus wyckii A truly incredible Catfish species, one that is well worthy of an aquarium all by itself, and despite possible seeing them mixed with fish on social media, take it from us, a solitary life suits them best. If you're looking for a large Catfish to live in harmony as part of a collection then choose a different species. Tel 01773 861255 for more information. | Wharf Aquatics
