I agree. It and others were on two Acropora. I’m a little scared on what they could be. It is barely visible to the naked eye.
Problem is that I have lots of pods in general. I dose phytoplankton pretty heavily and pods of all sizes, munnid isopods, amphipods etc are literally crawling on every surface even with a mandarin, sixline, and springeri in a 32 gallon.
