The TANK (actual Dimensions of the castle are 1 1/2 ft by 3ft)
75 Gal with homemade surface skimmer and home made 35 gal under stand sump with trickle and protien skimmer.
Update on DAS MEGAS he ate a clam last night did some excavating cuz i have a big pile of newly disturbed sand near the castle. Both Emerald Crabs are now kaput and this morning he was eyeballing me from near the open clam shell next to the new dig site.
seems to be unafraid and simply wary now.
