#whitespots

The bumps are fairly large and round, and they are only on the clownfish’s fin, and not on the other clown. Background info: this is a fairly stable tank, it’s about a year old now and the last addition of fish was over 8 months ago. I added a skunk cleaner a month ago, and I did a waterchange...

Just noticed my Sailfin tang has some small white spots on its back fin, is it ich? Anyone know what it is? He also seems to be hiding more than usual.
