Thanks for asking Adeeb! They are doing great..well..I think..prob is I never really see them anymore. The food I put out disapears and every now and then I'll see one...but I think I need to investigate and make sure they are all still alive. Though I'm assuming there would be quite a stink if one were dead.
One thing..on my lower land portion, the peice of plexi used was really short..I gave it some extra height with the rocks siliconed on. Well come to find out, the rock job doesn't hold tight like my plexi walls do, and when I fill it that full that lower land portion becomes a muddy swamp. However - the crabs seem to love this! Is it a problem? Is it ok for my substrate made of calci sand, sphagnum moss, orchid bark, and coco fiber to be wet?
