I would advise against danios. Some people have good luck with them, others find that they harass bettas or stress them out with the speed of their swimming. They also prefer cooler water (they can live in betta temperatures, but do better in lower temps).
Be careful with otos. They are very hard to breed in captivity, which means most specimins in petshops are wild-caught using cyanide. This makes them extremely fragile and many die in the first month. They need pristine water and huge amounts of algae, since it can be very hard to get them to adjust to eating aquarium food. Once fully aclimatised (about a month after buying them) they can be pretty hardy, but expect at least half of the otos you buy to die in that one month period.
Harlequin rasboras are good.
Also check out Endlers Livebearers, kuhli loaches, cory cats, bristlenose pleco (you could have one in a 20 gallon), platies, ember tetras, neon tetras, cardinal tetras and shrimp.
