don't be afraid to mention books here.... there are no nazi's on here that i know of... lol

as to the size there are people who keep salt tanks in 5g tanks. but bare in mind the smaller your water column the easier it is to crash the tank. i'm not pushing you toward a 120g but i would suggest going larger, just for the fact that a larger column is safer and easier to handle. if you go with a smaller tank remember everything will happen faster is water quality falls... as in if you lose a fish (say a small clown) in a 55g you will notice lil diff. but in a 10g it will nuke the tank, assumeing you didn't notice and the fish decayed in water.
