I use the fuge section of my sump to hold live rock and rummaging through to find some rocks to mount frags to I saw all this movement in the back corner. They looked like an army of Ants, I assume they are small copepods there were actually larger pods walking through them so maybe babies? anyways pretty stoked I had never seen this and thought they looked neat so here is a quick video of the critters.
