all but two of the mushrooms i removed from the rocks yesterday have turned to mush this morning. is that normal? what am i doing wrong? the two that are still good i actually ended up chipping part of the rock off so they were still attched. could i be cutting them wrong? i know you say i can't kill a mushroom, so why are they turning mushy and stringy? my quaranteen tank where i kept the frags smells like rotten fish this morning and the mushrooms are just stringing all through the tank.
