A very attractive, stunning livebearer that will shred any other fins accept ones own. Keep in a heavy planted basic tank with 8 or more individuals. If fry are to be raised they must be removed immediatly, preferably removing gravid female into separtate holding tank. The fry are very voracious heavy eaters that grow quickly. With all Brachy's, breeding is quite challenging. Reports have stated that these fish reproduce more quicky in cooler waters. Newly discovered in 1988 by Dr. Rosen, very limited info is available, and it is not very common. This is most certainly not your average livebearer.

This, too, is a livebearing toothcarp and not a carplike fish.
