Hi guys! Today I changed up my whole crab tank...new decoration, new cholla wood, new sand, etc. But as I was changing everything up I found 2 unhealthy crabs out of my 21 crabs...One was completely crippled...missing his big pincher, a leg, and is really sluggish and weak. Another one is also sluggish-looking and weak with one bent leg. After I was done with the tank and put the rest of the hermit crabs back in, one freshly molted pink crab was being bullied by a big crab. the big crab went and sat on the little crab, and then the little crab tried to move away from under the big crab and just came out of his shell! I took the shell away from the bigger crab that now had it and put it close to the baby crab who eventually, after much effort, got back into the shell, his leg falling off in the process probably because of the stress... I put all 3 of them in a spearate crab cage (those little ones you can get at those vacation spots that say "my hermit crab hotel" on them), to isolate them so no other crab hurst them with some mushy egg and coconut and water (fresh&salt). Did I do the right thing by isolating them all together?? anything else I should do to help them????
