Aquarium Advice Regular
I have 1 Zebra Danio (his friends died) and 3 White Cloud in my 20gal tank right now. I put the Zebra in quarantine by means of a breeder attached inside the aquarium with suction cups to rule out bullying from other fish but his condition has gotten worse and the other fish are starting to show symptoms.
What's happening is that the tail fin starts to narrow until the back is the same height as the front of the fin. This has started on 2 of my white cloud. As for my zebra, after this, part of his tail went missing (hence the isolation) and I have ruled out abuse from other fish as the cause because his tail fin has gotten worse. I should add that I haven't noticed any other symptoms besides the til fin.
here is a sketch (excuse my poor drawing abilities) of what the tail does
what could be causing this and how can I treat it?
any help would be appreciated
