Okay. I need some help here. I have small white bugs in the crabitat that as far as I can tell live in the substrate and I havn't seen them on the crabs. I need help though. I have a molter that just molted and is still very soft. I'm afraid that the mites or whatever those things are will eat my crab. I've got another crab that is acting normally. Now, I've seen some fruit flies in the tank. I think that the bugs came from them and are larva. The questions are; Will the mites eat my crab? Why haven't I seen them on the crabs? What do they (these bugs) eat? & ???? I need some HELP! What do I do to keep the crabs and molter safe if they do eat crabs? Help is appreciated. So, Do I move the crab or what?
