Hi , nothing precisely, the matter is that the first rock with three fluorescent green mushroom I put in the tank started to desintegrate and in ten days I lost them all. in some time four new mushrooms started to show on the rock with a small crab chopping parts from them ,I removed it and now the polyps are near half inch.
Now I have a new rock with about ten mushrooms and problem again, this time two seems to detach from the rock with some melting from the base and one is melting from the mouth out, and they are all almost white. so I want to treat them for all the possible pests , any suggestions !
