In my zebra danio tank, there is one beautiful longfin leopard danio (that I got on accident). This morning, I noticed that his right pectoral fin seems a bit crumpled. Maybe that's not the right word for it. It's more like it's folded a little at the edge. Should I be worried about this at all? It doesn't seem to be bothering him, but I would appreciate any suggestions.
