So a question, my RBTA has always been big and very open other than at night when it shrinks down to maybe a quarter of its size. But today mid day I was shocked to see it almost totally receded into the hole in the rock it is attached to. I just put a new fairly small toadstool in my tank last night. So my question is, even though they are a good distance apart, is there any way it could have gotten stung if the toadstool shedded or something. The RBTA is down flow from the toadstool. Should I move the toadstool?
