I have had a toadstool for a 2-3 years and it has always grown well and been happy along with the other softies, LPS and SPS. Everything has been fine, except for the toadstool. The long polyps stopped coming out a few months ago and it has been slowly shrinking. Algae occasionally starts to grow on top and if I brush it with a toothbrush the polyps might come out for a few hours, but that's it. Nothing has changed in the tank, so I'm not sure what's going on. I tried a few different locations, but that didn't help.
