[List Of Demands]

alright so yesterday i'm going about my day as usual i get up and check on the crabs, they seem fine, nothing unusual or anything like that. I go and help my mom do a few things and come back a couple hours later to check on the tank and WHAT DO I FIND? theres a circle of little tiny ants and i think they were dragging the calci-sand all over and eating it and whatever, but i'm not entirely sure what they were after. needless to say i flipped out i bought two new ones a few weeks ago that buried right after i got them home, my first thought was 'they must be dead and the ants are eating them' so i feel horrible for but i dug them up to make sure and they're fine it seems. one of them ate the exo and was up within a couple of hours, but he's since buried again. now my question is, will these ants hurt the crabs? they all seem to be fine and un phased by the ants, but i want to make sure that them living together for a few days longer isn't going to be horrible for the crabs because thing is, our car broke down, and the only other way my dad has to get around is his motorcycle, and going all the way to home depot on the motorcycle and carrying back a 50 lbs bag of sand is just not possible at this time. but my sister is bringing me her old turtle tank and will tank me to get sand when she comes over some time this week and i'll get them situated and all fixed up. I think I'm going to move them away from the window again as well cause i think that could be where they came from. that was long winded, but i'm done now. I just need to know if anyone else has had this problem before?
