Catfish Species
Updated September 23, 2018 | Author: Mike FishLore
The catfish species listed here are some of the most popular among hobbyists. These catfish usually are purchased to perform some sort of function in terms of fish tank maintenance. For example, these fishes are known for their scavenging abilities but they too need their own foods just like the rest of the fish in your tank.
Some stay on the small side (corydoras) whereas others can get quite large (pleco and columbian shark) and some can be aggressive (Chinese algae eater). They are all fascinating in their own right and can be great additions to the right tank setup.

Bumblebee Catfish
There are 2 types of bumblebee catfish, the South American and the Asian. The South American can be identified by the spot at the base of the caudal fish. This spot is almost like a square in the South American and a triangle with the tip towards the head for the Asian.

Kryptopterus Minor
Glass Catfish
The first thing to notice about the Glass catfish is that it has transparent flesh, which allows us to see the spinal cord and internal organs. This transparent fish is also a picky eater; it has been known not to accept flake foods with ease.
