Well I went to lfs and bought some more live rock (cured) and out of curiosity, bought 2 blue leg hermit crabs to see if my tank can keep them alive. It's a fairly new tank and they are the first introductions. I have high nitrates and am doing water changes and skimming to bring them down. ammonia and nitrites are 0. I've got brown diatoms all through the tank.
But anyway, my question is, do I need to feed these two crabs? or will they just eat the diatoms? I never thought to even ask at the LFS and they never said anything about it. To be honest, with my high nitrates, they may not even survive, but I thought I would try and see what happens. If they need food, what do I need to give them?
