as of right now i have 1 scarlet hermit (which i see once in a blue moon) i had bought 10 blue legged hermits ( but i only see a few at a time) i have my 2 clowns, 1 arrow crab, i cleaner shrimp, and my condy anemone.. im thinking of taking out my arrow crab because i think he killed my diamond goby that i bought yesterday, but other than that what other crabs should i consider? i was thinking about getting a emerald crab.. are they worth it?
