How many hermit crabs fit in a 30 gallon tank how many hermit crabs per tank?
Also, if you give your crabs exercise external to their tank, or give them regular baths, never dig up buried crabs to do this. Only take crabs visible on the surface. I also recommend that you don’t deep-clean more often than once every 3 months, to give your crabs a chance to bury and destress/molt without being disturbed too often by being dug up, cleaned (crabs maintain the salinity and acidicy of their shell water, cleaning it out before a crab molts is not a good thing in this crabber’s opinion).
