One of my zebra danios has a lump at the base of his throat, he looks like he swallowed a piece of gravel. The area looks pinkish. So far he is swimming normally, but is this something that will go away? Or will I have to put him down before he suffers?
I think that fish can have benign cysts. One of my black neons came with a lump on his side. I couldn't get him back out of the tank to return him to the shop, so I observed for a while before getting more fish. He's never had any apparent issues, none of the other fish have lumps, nothing's ever come of it.
