I bought 6 neon tetras the other day. I don't have a quarantine tank, so they went in the main tank. The tank is fully cycled, but there were not yet any fish in it. I noticed a little bit of torn and frayed fins, but nothing major. I figure that should clear up soon with the imporved conditions over being in the pet store. I'm still not very worried about that part.
However, I have noticed that one of the tetras has a gill doesn't look right. The gill plate sticks out quite a bit from the body, rather than being relatively flush with the body. You can see the red gills. He also has some white-ish mucus, or possibly fungus, towards the tail. His swimming seems just barely off, he isn't quite schooling normally, and the other fish are picking on him a bit. I am sort of thinking flukes, but there are no visible parasites (except maybe that mucus stuff).
What do you think it could be, and what can I do about it? I'm thinking about taking him back to the store, but if he has already contaminated the tank, I might as well keep him and try to cure it. Thoughts?
