ok as some of you know i have a small Q tank that i put snails in(i think i might buy a diff Q tank and just keep this one as my snail tank) i put them in last night with some water from my fish tank. this morning the water is cloudy. i put a peace of zucuni in there but i don't think that would cloud my tank. there is a snail in there that hasn't moved at all (i think its dead) can that cloud a 7"x4"x4" tank in 12 hours?????
