Well, I guess decapitating my big toadstool was a bit much. For about 3 weeks it has been going through the usual sequence of generating a new capitulum (sp?). However, now it is starting to degenerate at around the base, turning to a spicule-filled mush. The rest of the corals, in addition to some progeny right next to the parent colony, look great. Water parameters seem very good (pH 8.4, alk 3.5, Ca 400, NO3 2.5, in a 20 gallon that's been running as a reef for about 2 years).
Anybody have any ideas about what to do? I have been scrubbing the dead stuff off, but should I do surgery? Should I just remove it, and be happy that I have the small colonies?
