When i first got inc=involved in the hobby in January i bought 2 turbo snails from petco. they did not exactly look like the typical turbo so i am not sure. Anyway they seem to be nocturnal as i never see them. Just the other night i noticed them out they are the size of golfballs and i also started noticing some of my corals getting knocked over. Are these to large/ will the crawl across corals? do they eat mushrooms or leathers?
