6 gal eclipse tank, 3.5" DSB of southdown sand, feather caulerpa, 5 lb piece of Ultra Fiji, handful of rubble & snail shells, and a nice open piece of manono rock that he hides in, due to the openness of the rock & all the tunnels though it. Standard NO lighting for now, but will be upgrading to a 13 watt PC smartbulb. Filtration by the eclipse hood, weekly water changes, and macro export.
