Fish Setup

[SoldSpartan]

So I was wondering if you guys had any idea of setup fish wise for a standard 20 gallon tank?

There are many options for a 20 gallon, certainly more than could be reasonably listed. You could have a single larger (or territorial) fish like a smaller cichlid or a gourami for example, or have a peaceful community with multiple small species coexisting. A very general recipe for a 20 gallon community would be 1 "centerpiece" fish (a peaceful species of small gourami or dwarf cichlid for instance) plus one group of midwater schooling fish (small species of danios, tetras, rasboras, white clouds, etc) and one group of benthic fish (cories, small loaches, etc). Schooling fish should be in groups of at least 6, ideally 8+. It might seem boring to have only a few species, but ultimately a few unified schools will look better than a hodgepodge of fish (plus the fish will feel much safer too).

This is a pretty good (though not infallible) tool to get a general idea of whether a certain combination is feasible or not. Usually it is better to err on the side of understocking.
