well, I've got my tank coming togather, slowly, but its getting there. I was planning on doing a reef tank, but i really like lion fish,puffers, and groupers. Not to mention i dont have a light yet, so it would keep costs down doing a predator tank.. Display tank is a 46gal bowfront, has a 20 gallon sump with fuge,skimmer, and will have a alge scrubber.. With this tank size, what predatror fish would be ok, i know its small.. also do your guys think id be better off doing a reef tank with the size of this tank?
