Yesterday I was doing a water change and noticed weird clear goo on the rubber anemones in the tank. Today I took the anemones out along with a plant that I noticed had died. Now the goo is in little chunks all over the tank and stuck on the filter. I was considering doing another water change but the filter really needs to be cleaned and I know these aren't supposed to be done too close together. Does anyone know what this is or what to do about it?
