I'll second everything mentioned.
I've had all sorts of tanks for +35 yrs. Never salt due to the expense and a mostly overlooked fact the for every gal of water, freshwater will hold 4x the number of fish vs salt due to the oxygen available.
I want a busy, full of bright fish, low maintainance and low cost.
These are just a few quickly found.
And the options are endless: planted, cichlid tank (african/south american/rift lake), passive, aggressive, small/big fish, barb tank (great for small tanks), compatiblity issues...
