Clown with white tissue on base of dorsal fin

[Drakonis]

Here are pics, i inspected other clown and tankmates i see no signs of anything on them it almost seems like injury but to be safe lets see what you all think...

looks like the beginning of a bacterial infection. How long has it been this way? Is this a new clown? Any disputes with other fish recently? Was she QT'd?

I just noticed it tonight but i take frequent pics of tank stuff so i started looking for views of this clown and can say signs were present 5 days ago. here is best pic from 5 days ago...

This is a second tank i fired up to redo my main, fish have been here 11 days

No disputes that ive seen, all fish have been together since before xmas nothing new besides moving tanks. rock is from a fuge tank on setup they were moved from

looks like there was a bit of the infection already starting in that picture. Could be from an injury in the move. If it continues to get worse, then you can move her to a QT and treat with kanaplex. It's most likely a gram positive infection since it's moving so slowly.

If this clownfish is a recent acquisition, then it could be the beginnings of Brooklynella: https://www.reef2reef.com/threads/brooklynella.247938/

However, if the lesion doesn't spread and remains confined to one area then I agree a bacterial infection is more likely.

Probably bacterial then.
