i just got 9 snails, 5 margarita, 1 turbo and 3 astrea. it seems like one might be dead, its foot is pulled in and its not doing much of anything. i was wondering, how do you tell if a snail is dead? what lighting should i have for them? is there enough food for them on the live rock/sand (30g tanks, 40lb rock) one is on the heater, is that bad for it? i just want to make sure theyll all be ok, theyre really cute. thanks!
