The urchin is really nice! And as always the tank looks great. Next time the dollar per gallon sale comes up in gonna grab a 40b and buy my rock from amazon. My local petco is actually pretty decent. The staff is normally nice and helpful. There is a good amount of test kits/filter media/fish. They happen to sell love rock for about $2.50 a pound. Just got 21lbs of it for a ten gallon an it came out to like $40.
