black dots on clown

[Delphinus]

I had an ocellaris that did that. At the time, nobody was able to tell me what it was. Not having read the text of those three links I don't know what people are saying, but in my case I am fairly certain it was NOT a case of the fish being suddenly stung by the anemone.

In my case though ... it could, however, have had something to do with the fact that it was a male turning into a female. One day the spots disappeared, basically. Took a few months but they did eventually just disappear. Also eventually my two clowns became a mated pair. With the "ex spotted" one being the egglayer (thus female). But previously she had been the "he" in a different clownfish pairing.

So I don't know if it had anything to do with that. Maybe. I can't be certain.
