Went out to buy 12 margarita snails to do the job. these are for the walls of the tank. some of them are pretty good --- the trail that they are moving along is totally cleaned, however, some of them tends to move towards the rocks and hide there. Next to tackle the sandbed. will check out on the hermit crabs this weekend. Thanks for all your advices.

is the hermit crab compatible with my livestocks? tried a couple of snails sometime back but after a while they seems to die. is it suppose to be so? how about the black spots i mentioned earlier? what are they?

sea cucumber, hermit, as in hermit snails? which fish shop to go to get all these snails at one shot? thanks.
