That is a samurai gourami, I was going to start a species tank this past spring and didn't get
the chance. They are mouth brooders and need to be kept in a small group, not 2 like most gourami's.
The female is the colorful one and they're a bit easier to keep then the chocolate gourami's. Still
thinking of doing a tank for them, will have to wait for spring again, I think it's too late to ship.
azgardens.com had them and tell you about them, interesting fish.
