Ide realy like to set up a fish only 30g. Ive already got the tank and salt(for my old brackish tank)but have no expirience w/ salt water. Would like to know some of the basic supplies(what do you all use;filters, to skim or not to skim...) and if maybe a FOWLR would be easier to take care of. What are good fish for a first timer?...damsels?clowns? can i put in inverts if it is fish only? Thanks alot!
