I dunno if I believe that, it says that Betta's can live with Danio's and Guppies. I'm so confused. :-\Check out this chart:
I believe it specifies that all species of Cichlids are a definite No on the compatibility. We just have to face the fact that the Betta is socially stunted and does not do well with other fish. If you are looking for a community tank then perhaps a Betta is not your best choice. A Betta is pretty much of a loner and it is not his fault. Just accept the fact that you are going to have to be his best buddy if you buy him and perhaps have some small tank mates that are not the most spectacularly showy of fish but peaceful quiet little shoaling fish who will help to keep your tank clean.
