Albino catfish (a genetic anomaly causes their lack of pigment) are not uncommon. They are no different than any other of their species except for the coloring (they are just as tasty). They are actually preferred over 'normal' cats in the commercial industry because of their beauty (for aquariums) and their visibility (for stocking lakes). The latter is their downfall in the wild. They are so visible to predators, the albino cat seldom lives long enough to become an adult. GOOD CATCH!
