Nice catch, where'd you get him? You know, this is one of those fish you can keep without a hook... The big colorful ones are males, they also get tuburcles (lumps) all over their heads when they're breeding. They're everywhere around here, and look good in a big school. If you want colorful minnows, there are lots of red shiners around here, too. Texas Logperch are also great tank specimens. Good luck, you'll be surpised with the variety of stuff you can catch in our part of the world. If you hook a Sailfin Molly, let me know-that could be a first! Hint-Coleto Creek is full of big ones.
