I posted a while ago about how my betta had a lump in his tail. I thought he was sick & going to die or something, but he's acted normal. He was fine. But now he has some type of growth on his chin right where the triangle goes to a point. It's the same coloring as his fins (dark purple/blue), and I don't know what is going on. I'm going to end up with a lumpy bumpy-looking fish. I can't tell if it's bothering him. He's acting normal. Has anyone seen this type of thing before?
