Hi everyone. I got 4 betta females about a week ago. 3 of them of perfectly fine and happy. One has a problem though, well I don't know if it's a problem. Her one side, close to the face, looks swollen. But only one side. I was looking at pictures and she almost seems pregnant but she can't be. I also looked at dropsy and it looks nothing like that. In the week I've had her it hasn't grown or anything and she eats like a pig and never stops swimming. So I'm not very worried just a little confused.
Any suggestions would be welcome :)
