They are found up north in china, cold water tolerant, I've collected this fish myself in the past, very rare in the hobby, aquarium glasser in germany had a few sometime back, as a new import. Here are a few pictures of mine that I had, the males were really pretty, too bad I don't have them anymore, and Masheer, they're not monsters!!!!
Guess this one, and I'm looking for supporting data and pictures to go along with it. There are a dozen or so species in this group/genus of fish, mostly found in Africa, please submit, and guess, winner can have next round Happy playing
