I just added a toadstool leather coral yesterday, and while I didn't expect it to be fully opened/acclimated after one day, I didn't expect to come home and see TWO dwarf red-legs wandering around on it!!! Right now it doesn't look like they did any harm, and I just knocked the hermits off of it and down to the sand. Is it normal for hermits to climb on toadstools??? Can they damage or kill my it??? If so, how can I prevent it?
