Clownfish with bump on side/looks like pimple.

CenCalReef · Apr 3, 2021

Of all the threads this is definitely the area of the forums I hoped to never post in but here I am seeking some help or info or lead as to what I may be looking at or dealing with. I have two clowns both “designer” clowns. The male of the two seems to have a lump on the left side that looks almost like a pimple. It is not ick. It seems to be pretty good size through the aquarium glass I would say about 1/8” in diameter or the size of the O on your iPhone keyboard. I assume it can’t be more than two weeks since this has developed as I consistently stare or do maintenance on the tank only today did I notice it. I will also add note that while cleaning the glass I dropped my stainless tweezers into the tank as I tend to rest them on the edge of the glass and overflow ‍

I attached some images and excuse me for the disco blue affect I don’t have a filter and if need be can take pictures in white light. Any ideas on what may be going on.

It’s one of two things:
Either a reaction from a sting (coral or anemone) or Sporozoasis tuberosa - Called nodular disease, ball or rice kernel shaped nodules, caused by Sporozoans.
