So I have a tank with 3 female bettas. It used to be 4, but one sadly passed a few weeks ago. She had several huge white lumps on her head that appeared out of nowhere, and she died in days. I was going to post it here, but she died before I could. So I thought that was that and moved on. Now two of the other bettas have problems as of today. One has gone extremely bloated and looks like a balloon Molly, and the other did the same and also has a huge white lump on her side. It almost looks like her insides are spilling out of it. I’m really concerned, I don’t think either have very long. Only one betta in the tank is unaffected, and I don’t know how to keep it that way. I do have a new tank, but I haven’t set it up yet and it could take a while. The tank hasn’t been the best lately, my mum has been feeding it as I haven’t really been feeling the best over the last few months. I think she’s only cleaned it once. Can anyone help?
