I've had this nice green mushroom on a piece of live rock for about 3 month
When I came home today it wasnt on it anymore
Looks like it detached it's self why would it do that?
Every now and then my ricordia and mushroom also detach and float away, sometimes landing behind the tank. No way for me to get them out - and they die. Oh well
How's your water quality and hte other corals? If everything looks healthy and open then I would suspect just one doing it coud be nothing. If you had a bunch do it then your water quality could bre the problem.
