What will you be feeding them? Mine seamed to starve on a diet of only MTS.
Biollante, have you ever owned an assasin snail (Clea helena)?
We (culture) a variety of snails for puffers and others, good use of old fish food.
we also culture and inoculate many tanks with various worms that a couple of varieties of so-called assassin snails seem to eat. they are opportunists will also eat small shrimp.
seem to prefer fine sand, will bury themselves and seem to dredge. we suspect they also eat most things they find, round worms, blackworms, young other things. population growth is explosive.
If you have multiple tanks care should be taken to avoid introducing into other tanks.
