Catfish include the body of Siluridae, which is actually off springs of the Catfish. The European catfish, including the naked skinned fish is kin to the Asiatic group. The translucent layers of skin makes the Siluridae group one of the less desired aquarium fish.

This particular fish has not been bred while in captivity, and its breed does not have a particular or preferred water condition. Kin to the Glass Catfish is the Mockokidae. Mockokidae derive from African waters. The naked Mockokidae, as well as many other catfish are helpful fish, since these fish feed off biochemicals, which makes these fish scavengers.

The fish will eat other dead fish, as well as decomposed macrobiotic bodies. In addition, catfish are responsible for maintaining tank photosynthetic organisms, known as algae.
