My smaller clownfish showed up with those two (maybe 3) dots about 4 days ago. There was no new fish in the tank in the past 2 months. Only the BTA and a frogspawn is new to the tank (introduced them about 3 weeks ago).
The bigger clownfish and the fridmani have no dots on them.
They are all eating as much as they can and there is no weird behavior on the affected clown...
Should I be worried?
