I got three percula clowns at a good LFS
on Saturday and have had them in a 10 gallon QT since I got them. All three eat fine and don't appear to have any signs of stress.
Two of them stay pretty much together at all times, and the third is pretty much by himself. He'll swim over to the other two, but most of the time is just swimming by himself.
Upon closer inspection, he has some physical characteristics that have me concerned. The first is his dorsal fin - it has been eaten away quite a bit. (The other clowns did not do this. They were in a tank with a damsel at the LFS
and was this way when I got him) My question is, will this grow back.
Second issue is a bit harder to see. Towards the bottom of his center white strip, there is a blue coloration on both sides. It is almost like I'm looking through his skin to his insides. Also, the blue area is a little swollen. The other two do not have this blue-ness. One of them has a bit of brown in the same location, but not blue. Is this just because they are so young? Is there any known disease that would turn a portion of the skin blue?
I'll try to get some better pics, but these are the best I have for now.
Thanks for any help you all can provide.
