Hi all i really want to get into the salt water tanks but dont have a clue as where to get started.I would like a 45 or 50 gallon corner style tank because i dont have the room for a 55 long tank or anything that long.Would a corner tank be good for a sw tank?Also ive been reading some of the other forum questions and i dont know what live rock is or a reef tank.Do the live rocks have stuff growing off of them?I dont want just a fish tank.I would like to have those rocks if they start growing things on them or the reef setup.Also whats a good book i can get to read on setting up tanks for newbies and what would be better for a newbie starting a sw tank the reef or live rock.Thanks for any info
