Well, that'll make the wife happy. I've been making noises about a 120-150 gal. tank for natives, but if I can do 2 warmouth in a 55, my dream tank can happen much sooner (and cheaper!)
Neg... Florida Warmouth, reason I know is because I kept a few from my casting net adventuring and started learning about them. The sizes I've seen I don't think I'd try anything smaller than 55gal for one guy long term. Mine all did very well in a 120 with other Souths and Centrals. They tend to just "hang out" but will show some serious facial war paint and muscle if challenged. They have a very awesome preditorial mouth structure shaped primarily like a largemouth. Body shape I would say closesest resembles a huge sunny without the such pointy mouth or maybe a northern rockbass. The fish is pellet trainable but I found it to be much easier in a shallow tank because of the fact that it liked to just chill at the bottom gettin a lil R&R. Great looking native and seems to be a gentle muscle bound guy.
