It's not as durastic as it sounds, actually! I have a 2.5gal tank that has (what I thought was) 3 female bettas in it. They were in my 45gal, but they didn't like it because there was a current from the air stone. So I bought them their own tank, and they are now fine. Well, in my 5gal that houses my male crowntail betta, I have just spawned him. Yesterday, I put the female back into the 2.5gal, and noticed that there was a bubblenest in there too! It wasn't a 'normal' one though. It is a sort of lump that sticks out of the water, but obviously made from bubbles. I've realised that my biggest, most colourful 'female' is actually a male! Should I buy him his own tank? He has been in this tank for a few months now though.
