cool deal i just saw the Red Mithrax Crab and just wanted to add a few to my tank I have 6 emeralds in my tank and they never cross each other... One MONSTER one i have tried to kill my decorator crab the other night but once i broke them up they have not crossed each other again since... So i might get 3 or 4 of the red ones to add i have plenty of rock for them all to have ap lace of their own
My emeralds are great I have one real monster one that likes to get on the tip of the highest rock in my tank and swing his arms like king kong... Plus this group I have in there now is a work pack they keep everything looking great and are always on the move picking from rock to rock
only problem is once everything is clean, they will go hungry, start attacking each other, and possibly your fish. Monster is in the fuge because he was taking swipes at my fish.
