At the right time of the year any aquarium store should be able to get them for you. They are only like $7.00 each, they are legal, they act like largemouths, they are a prettier fish, and you can have more than one of them in the tank without worrying about them killing or eating eachother (unless they are significantly different in size).

I have two babies right now and they are very cool. One is very active while the other is more of an ambush feeder. It's strange to see how different they are. I'm hoping it means one is male and one is female.
