My encrusting Montipora is losing flesh/polyps in certain areas.
Since I have it (4 months) it has only survived, not grown or shrunk. It has started to get algae around the edges 2 months ago and one tiny patch in the center. Now since 2 weeks entire areas of polyps have disapeared. I had it in about 180PAR and have just now moved it down to about 120PAR.
At night I see amphipods eating on it. I assume they are eating dead flesh? I also have snails go over the entire frag on a daily basis.
I see NO nudibranche. It is not in the vicinity of other coral. Tank parameters are as stable as I can get them on a small tank like this. (Alk swings maximum +-0.2 per week). Everything else is growing very well. Mixed tank. (other SPS = Pavona & Pocillopora)
1 Clown, 1 Cardinal, 1 Coral Banded Shrimp, Hermits, Snails & 2 Bubble Tip Anemones.
Is it not getting enough light?
Any ideas?
