Once took on a trio of "Cambodian" Betta in response to an emergency. They were plunked into a well planted, well populated community tank. Space proved to be another aid in getting them to peacefully coexist.

The male cruised the front, center stage. The two females hung out in the wings, except at feeding time. Their finage was not perfect, but still was attractive. I was amazed when they began breeding like crazy a month or two later. As in nature, when they were ready, the females sought out the male. :)

That is an interesting Betta site. A lot of work was put into the site and into the Betta photography, not to mention caring for all those Betta strains, breeding them, probably using some sort of stud book to track the Betta breedings and sort the youngsters out.

And we think that sorting out and separating guppies can get involved! ;)
