A neon tetra school is a must-have IMO
. Depending on where you get them, they are pretty easy to care for.
Any type of tetra is usually good, but as always, there is some exclusions to beginners. Look up some livebearers and tetras, and we shall help you in your research (Should you have any questions).
My 30 has hi fin platies, habrosus corydoras, corydoras trilleanatus, and a Bolivian ram.
Harlequin rasboras, sparkling gourami, small plecos, otocinclus, lemon tetra, diamond tetra, serpae tetra, and many more suit a 30 gallon.
If you figure out some that you like we can talk about what will work together!
