Most of the compatible fish are schooling fish that do best in groups of 4-8. This would include Neon Tetras, Ember Tetras, Harlequin Rasboras or White Cloud Minnows. That many fish may be too much for a 3 gallon tank. Other non-fish option include Ghost Shrimp, Zebra Snails or African Dwarf Frogs.
