the stuff on the gill was on the edge. it would move with the gill when breathing. yesterday they were clear, like an air bubble, today they have shrunk and are pink. but the pimple on the tail is unchanged.
the fish is new to me. I bought it at That Fish Place on Tuesday the 26th of August. so its been just over a week.
the tank is a 55 gallon, it has been up for about 6 months. started with two damsels, added 2 clownfish a few months ago, this is the only fish we have added in awhile. also have a turbo snail, coral banded shrimp, anemone, lots of live rock.
I doubt my tank got this fish sick, maybe the stress of a new environment but not likely since it has places to hide and room to swim versus the tiny space it occupied at TFP.
I don't have a test kit other then strips. I make up for it by changing the water weekly (which makes my wife crazy) and trying to keep the bioload low. I want a nice coral tank with a few fish, the wife and kids want pretty fish to look at, everything they like is not reef friendly.
I appreciate any help or advice anyone has.
