if i see that my caulerpa and pod population seem to be affected, i will move the crab into another chamber in the sump (there are three other partitions available in theory). however i expect he is more interested in eatings worms, and the fuge has a. a 7" dsb and b. a huge pile of rocks that i doubt he will ever fully infiltrate. and with 220 lbs and 4" of sand in my display tank, i think he'll be alright.
