Is this something I should be worried about?
I have a male betta and I’m thinking he is at least 2 years old, and maybe even approaching 3. He is very healthy, active and eats normally. Only thing is he has diamond eye, so I have to help him out with feedings, but once he sees the food he is all over it. He knows his tank very well and since he can’t see that great I am not going to change anything around.
Today I noticed after I fed him a small bump on his side, and slight pineconing of the scales. It is only on one side. I didn’t notice this before I fed him, but I might not have looked hard enough beforehand. He ate perfectly fine and is not showing any signs of illness. Is this a result of feeding him or do I need to start treatment for something? I tried to get photos so I will put the best ones here but he moves around so much especially while I’m at his tank it was hard to get a good picture. Thanks in advance!
