I was talking to the owner of one of my local lfs's about getting a few (3 or 4) female bettas and putting them in a tank. He told me that 60% of female bettas die if they don't breed because they need the male there to push out the eggs from them or else the eggs rot and kill the female. Is this true? I've never heard it before and hes also a bit of a (insert nasty word here). What do you all think? Have you heard or experienced anything like this?
