I have a glo fish (danio) with dropsy and I noticed that another of the glo fish is starting to get deformed. They haven't really blown up yet but their tail is pointing down and they are getting a hunch back.

Do you know if this normally sticks to one type of fish or does it take over the tank?

I was going to let nature take its course but if it will affect other fish these guys are going to going to have to go.
