Hey well my question says it all. I want to start a 20 hex s.water tank something small for now. I just want a few coral , a couple of small fish and maybe a critter or two. Ive been researching through out the net but Im still confused as to what exactly I need to start. Your recomendations would be appreciated. I already have a brand new canister filter (Fluval) and a low light system.
