Wart on Dwarf Puffer fish?
I just noticed that one of the Dwarf Puffer fish has a bump around the middle section of his body. How the bump looks is difficult to describe, so the closest thing resembling it would be a wart like how someone would get on their hand. Of course not that large. I would say slightly smaller than the size of his eye. It does not look like an open wound or infection and he seems to be in good health. The bump is the same color as his body. Anybody know what this might be and what I should do? It is very strange to me, I haven't seen this before on a fish. Thanks
