Hi all, this is my first post here. I’ve been working at a pet store for a little over a month, and someone came in and surrendered a betta yesterday. She was in a small glass vase with 2 tetras. She’s also pretty overweight. I just put her into her own tank this morning and noticed a small white bump on her belly. I’m not very experienced with fish, and I’m anxious that it’s something bad. I don’t think it’s ich but I’m not 100% sure. It’s the only bump on her, and it almost looks like a white head?
