I wonder if your fish is Pimelodus albicans as mine was. If you will, check out the thread on mine and the links therein to Kie, Amiidae, and Rico Richter fishes among others are helpful too. http://www.planetcatfish.com/forum/viewtopic.php?f=13&t=30240&hilit=albicansHere is my Vaillanti, it's probably close to 12". It is an exceptionally slow growing catfish. I've had it for close to 2 years and in that time it's grown maybe 1". My buddy who gave it to me had it for a couple years and said he got it around 7-8".
