These are beautiful, graceful fish. They can be kept alone or in pairs and are generally peaceful towards other fish, but may show signs of aggression towards each other. All in all a wonderful fish.

I have a Cobalt Gourami and find it very aggressive to the other 3 species of gourami and the 2 Angel fish. It doesn't seem to bother with the smaller fish though.

The fish in the pic is what I've heard called an Opaline Blue Gourami. Whatever common name you hear it called, it's still a Trichogaster trichopterus, not a Colisa lalia.

I have a cobalt blue, she is peaceful to all the other fish in her tank, and tends to act a bit dopey.
