Black Ocellaris Looking Pitiful

[chrislower]

I am currently starting up a new tank and after several weeks of cycling I introduced 4 very small ocellaris hoping that I could get 2 mated pairs in my 100 gallon tank(I known this is a potential risk). All fish were introduced at the same time from the same lfs so no quarantine. After two weeks I have 1 black ocellaris that has what looks like fraying on the fins and something very odd on the abdomen. All the other fish including the chromis are doing great. The one clown is swimming and eating like normal but looks horrible. Is this aggression or lymphocytes or ich?

Ich is a possibility. Any other fish have white spots on fins?

That isn’t ich. Can you try for a closer photo under whiter light? I can’t tell if this is lymphocystis or a bacterial disease....

@Jay Hemdal - Below is a larger image I blew up. My gosh- looks like bacterial (cauliflower like)

See if this is any better. There is also a white damage on the nose.

That looks like severe lymphocystis, a virus that causes the fish’s skin cells to become gigantic. It is only fatal if it involves the fish’s mouth (you fish may have it there) bad enough that it impairs feeding. This will go away in about 8 weeks or so, there is no treatment. That said, fish can have multiple diseases at one time, so you need to watch every non-quarantined fish very closely.
