Hello! My nem has been on the same isolated rock at center of the tank for 12months. Ive been able to restrict its movement by turning the rock untill it finds the nice big hole again for its foot, (tries to move every cpl months) this time its moved in the night & is now on the main rock formation, will it destroy every coral in its wake??? Its a fair size tank and has a bit to go before im worried about the wavemakers, clowns are still hosting the rock lol, but dont think they are aware its gone yet lol as lights still out (looking under red) thx
