I had another pair of bettas spawn yesterday afternoon. It is my blue and white marble male, to a red cambodian *the female that spawned last week to the crowntail, but infertile* I had hoped to spawn this male to my melano geno female....but she wasnt interested, so I put this female in the night before, and the next day they had spawned. This is this males first spawn...and I think they are infertile also. He makes beautiful nests though. His jar was always full of nice bubble nests. When I put him in the spawning tank, within an hour he had the area under the foam cup full of bubbles. I'd be happy if just one of these eggs hatched!!!
