Yes a reef(corals,fish,inverts),I didn't get fish into it since I have 5 siblings(newborn to 13) and couldn't be driven out of town(3 hours) but it has all the nice critters and such just no fish or neat corals. And I'm moving so I can't justify spending money on fish or corals now.. But the water is perfect and all worms,feather dusters and whatnot are happy. I did get the live rock from a local store but the guy is a rip marine fish wise... It's a very expensive hobby,I've spent $500 just to get a setup thats appropriate for fish and soft coral.typically a 55 setup for SPS,LPS and softies go for $1000 just for Live rock and the equipment(tank included) Thats it ! Crazy bump I'm a newbie to bump maps so that will be perfect until I get better at bump map creation and whatver else.
