Sailfin Tang


New Member

Can someone help please.

I have a Sailfin, circa 7 years old in a mature reef aquarium with several other fish. Noticed for the last month it has been showing white spots/lumps on its pectoral fins (and only fins), initially only 1 however a few more now.

Fish is otherwise healthy, no new additions in aquarium in last 1.5 years, aquarium has stable unchanged parameters in the last 2 years. No other fish show any other problems.

Initially considered may be some sort of bacterial infection so treated system with a reef safe anti bacterial treatment, no affect.

Any suggestions?
