The catfish family have whiskers. After that they can be nano tank size or tank busters. This family is large and includes corys, synodontis, plecos, algae eaters, and tons more.
The group is so large and such a big part of the aquatic trade that we had to create a shopping selection, but please note very few of these species are alike - except for the whiskers. This is also a great section to find monster fish for large species aquariums. Another great place is the oddball collections, sorted by regions - African Oddballs, Asian Oddballs, and South American Oddballs.
