i know marc personally, he is an AWESOME guy and he sells quality rock...don't EVER purchase 'live rock' it's just too big of a risk. Personally i wouldn't even buy my clean up crew from petco either, the only things i ever purchase from petsmart/co are supplies...brushes/food... and that's if its a absolutely necessary...otherwise i make my own food and have magnet cleaners.. lol
Marcorocks.com is the way to go. Buy 30lbs of it and call it a day.
Cichlid king is dead on with the sand, you want a DSB (deep sand bed) which basically on the bottom of the tank is over 3".
Be careful of mixing hermit crabs like that...sometimes it works...but in my experience some of the differed colors tend to go cannibal. (my blue's somehow took over my red population very very slowly.)
