Unfortunately of the information you have provided, nothing leads to a proper ID
. Copepods, amphipods, mysids, epitokes, spirorbids, sponges, larvae etc, etc... All match these descriptions. The fact your fish may have developed signs of C. irritans
(if that's what is is/was) may simpley be coincidental. Having ideal conditions doesn't prevent animals/parasites from reproducing either.
Also the other pods and critters that live in my live rock, are out all over the place. They are usually only visible at night, or maybe you will see one or two in the daylight. But now they are out in full force eating the small white organisms.
Normally reclusive critters within your ecosystem will become much "braver" for lack of a better word in the absence of predators. If there are little or no fish in the tank, these macroscopic/microscopic critters become active during the day and will feed in the open.
