So just a little update. .. besides the coral doing great, I still have a patch of dead tissue.. Strange thing is, the other day I found a blue legged hermit crab on the dead tissue. I figured it was a fluke. I removed it, and the next day it made its way back to the dead tissue. Anyone ever heard of hermits munching on sps tissue?
Even more strange, a day after I removed it (again) I found a few miniature serpant stars covering the area of dead tissue. Now I'm pretty sure those miniature serpant stars don't eat SPS tissue. Any idea of a tiny parasite the miniature serpants and blue legged hermits might eat?
