So I went to Petco to get my baby Betta. We could not find them so we began to look at adult Betta fish. I saw this very interesting fish. He was a Halfmoon Plakat red and white spotted.. I was about to check out and take him home instead of a baby betta. Then in the line I noticed a bump under his chin I believe. I freak out since the place was closing soon (we had no idea) I put him back and left afraid he was unhealthy as I read bumps were unhealthy. Was this mild lump a sickness or something?
His lump look like the one bellow. I'm confused. I love that fish. Should I go back and get him if I can? I would say his lump isn't that big though. Is there a medicene to solve this if it's an issue?
