I had the same problem a while back- I got up in the middle of the night with a flashlight and found one of those redish brislte worms doing a lawnmower act on my greem monti cap (which I prevoiusly thought was dying off on its own)- I had a population explosion of these beasties and they were turning predatory on most of my corals- argh! I am not saying this is your problem but IT DEFINITLY HAPPENED TO ME.
As far as an remedy I added an SMALL arrow crab (watch out he may eat your snails) and an coral banded shrimp- I combined that with reduced feeding and everything seems to have returned to normal. One thing I found interesting is that one day after adding the arrow crab all of the worms pretty much went undercover- it was almost like they could sense him in the tank! |
