A little background....
Picked up a free 10g tank yesterday. Inhabitants were a CAE (about 4-5 inches long), a betta, 2 glow light tetras (I think...they school with the neons), 3 neon tetras, and 2 peppered corycats. Couldn't really see the fish when I picked it up...they were all hiding. I assumed from the CAE since she did mention that he picked on them. Got home and removed the cories and the CAE from the tank. Then I noticed a white cottony spot on one tetra's tail and a protrusion on another tetra's mouth.
I think we can all assume that their water quality wasn't great since there were so many fish in the tank. The cories are full grown, and the CAE is large. I didn't test their original water . The old owner was a a clean freak, and I think she kept the filters changed and the tank scrubbed clean (maybe too clean). I don't know her water change routine, but I kind of doubt there was one. The water parameters are perfect now that they are here, and they've had a 85-95% water change.
What do they have? How do I treat it? Is it contagious?
Thank you.
ETA that the one with the tail problem is missing a little bit of his tail where the spot is. The spots look cottony.
