The general rule is fish keeping is 1" of fish to 1 gal of water. Bettas are 1.5 to 2" long. However, even female bettas will fight until they figure out their pecking order, so give them more room than that and plenty of hiding spaces. Honestly, don't get more than two, and even that may be too many if one of them is a bully.

The fish are not bad together. But way to many fish for a ten gallon tank. You put one fish for every gallon. They will probly do fine but you will have to clean more.

Can Betta fish co exist with other fish?

It is a misconception that betta fish do not get along with other fish. While intolerant to their own species, bettas can get along with other fish so long as they are not easy to mistake for another male betta - such as fancy guppies - or fin-nipping fish like many tetras that often go for long-finned fish. Female bettas can be housed with guppies, however.
