What fish can live in a 10 gallon with a snail and betta?

I have a heated and filtered 10 gallon tank, with a male betta fish and a snail. What other fish can I ad without it being overcrowded?|||Bettas should never be kept with other bettas (although I've done it once or twice...) and they are compatible with the Bala Shark, Corydoras Catfish, Glass Catfish, GloFish, Molly, Pearl Gourami, Platy, Rainbow Shark, Red Tailed Shark, Swordtail, Three Spot Gourami, Upsidedown Catfish, and the Zebra Danio. I have also kept bettas with guppies, green spotted puffers, and figure-8 puffers, but those are unlikely pairs due to the fact that the puffers nip at tail fins, and the guppies might upset the bettas.|||another female/male bettas since the bettas hates other species acept snails, pleco, algae eater, cory cat, and thats all but if you get a female/male with your female/male betta and they mate it will be hard to care for babies|||Pygmy corydoras, kuhli loaches, platys are all generally ok with the betta and a 10 gallon tank. It also depends on the bettas attitude some do not like other fish while others don't mind.|||Check out the chart found here : http://itsjustbetta.blogspot.com/2011/09鈥?/a>|||You can add 6-8 Neon teras
