Well...In all my years of keeping fish I've never seen this before....My Zebra danio has a big lump on its head, right on it's forehead....It's pink, and about the size of one of its eyes. Anyone have any idea what it is?
 
A tumor? :o I have no idea, but I wonder if internal parasites or something like that could cause lumps... How are the other fish?
