Dot on clownfish

[mattb2989]

Hi all. My male clown has developed a single white dot on its pectoral fin. Recently done 116 days fallow. Fish have been back in dt for a month now. These fish were treated with cu and the observed for 30 days prior to going back into dt. Fish coming in get the same treatment and nothing new added to dt for over 2 weeks now. Any advice on this single white dot. Its hard to see under whites but blues its clearly visible. No other fish in dt showing any spots. No scratching etc from any other fish also

Well, that looks way too large to be ich. May just be a broken fin ray. I would just observe for now.

Thanks jay. Really dont want it to be whitespot or velvet. The 2 clowns are having spits and spats atm. Think theyre deciding whos male and female
