Ha, yes i litterally ripped it off the bolder down the beach (low tide), though ive noticed one has died partially, (crab been eating at it) as my LR is off the reef fall (stuff washing up on the beach), its full of crabs and cant i am pulling them out daily, one bugger a blue clawed one is at least 50pence in size...
Sure i also have a manta in there...
Anyway, moved the damaged one to just below the water line, all others are doing just fab !
