Can a female betta become depressed if she as been in a sorority for months and is now the only one in that tank? There are other tank mates but she is now the only betta girl. Or would more slower eater and just so laid back not swimming around constantly ( not lethargic) as before a sign of less stress? ZZ just isn’t as zippy as before. But she was the beta not alpha or omega but always trying to be above the omegas. So I’m just wondering from those that has had sororities and no longer has it or still has it and may have some insight on this.
