Hello people,
Lately my yellow Acropora Granulosa is not doing very well. I has lost its color and became dark brown. I had some PO4 spikes lately and was thinking it was the problem. After some good inspection on the coral and taking some pictures of it I have found at its base two things. There is one Vermedit snail close at its base that I plan to remove asap with the next water change but I noticed at its encrusting base to white holes (highlighted with red arrows). These holes seem to coming out from the Caribsea live rock and drill through the encrusted skeleton of the coral. Can you help me on identifying these critters. The coral is in there for 4 months, it was cut well above its base and dipped prior to the introduction to the tank.
