i would say that the bacteria thing is a bunch of bull as these are bit marks for sure. The errosion of fins from bacteria start on the outside and work inward degenerating the fin a a more even pace. not as deep cuts as seen in your pictures.
Right, it certainly isn't bacterial. Something is clipping his fins.

Well, keep in mind that he didn't have my pretty pretty pictures to look at, just my description of what was going on.
At this point, I did put the SeaChem PhosGuard product in a filter bag in my sump. My phosphates were high when I tested them a few days ago. But I guess I will go ahead & hold off on the antibiotic for the time being...

Ok, the red crab is still in the sump. I did not notice any new chunks missing from the clown's fins today. The firefish is still unharmed. Perhaps that crab is the culprit... Hopefully no more injuries occur tonight.

Also, I would not add antiobotics to my DT. That is what you need a QT/HT for. The antibiotic will also kill good bacteria which is what your biological filter is you did a cycle to create.

Yeah, I did not do the antibiotics. There is no point obviously if it was something attacking the fish. I do not CURRENTLY have a QT. When I set up my new sump/refugium this weekend I will convert the tank that is currently my sump into a QT.
