I’ve had this one for a while and it has settled in nicely. It’s always open and flowing in the current. I noticed this the other day after irritating it while picking algae out of the tank. It is several white patches where the polyps/tentacles come out. Anyone know what it is?
The white spot in the bottom left corner, is that on the toadstool as well. It looks the same as the ones on the crown. Could be bite marks or if they are consistent or possibly something dripped on to it, do you dose possibly?
