Mmm, yeah they can get along with otos SOMETIMES, like another said it depends fully on the bettas temperament and it's highly likely they wont get on well. Some bettas can, others cannot get along with anything else....like some get along with snails, others will rip them out of their shells and kill them if they can, or constantly pester them...and sshrimp are pretty much lunch for bettas.
The other problem is, otos need groups of five or more and to be kept in 20+ gallon tanks. Like cories, they're social, and are very sensitive fish. If they don't have proper space, food and a proper sized shoal, they can get stressed out and die.
In a ten gallon, bottom-dwellers need to be kept to shrimp and snails, critters that can handle smaller tanks and don't need large groups. Even pygmy cories don't do well in tanks that small. It wont be able to handle the bioload from a betta and five otos either I don't think...bottom-feeders and carnivores like betta have a pretty high bioload.
Find a new home for the oto and get some Zebra Nerite or Tiger Nerite snails. They're pretty hardy against betta. You MIGHT be able to get a couple African Dwarf Frogs with a betta(no more than two or three, and they must be in groups of at least two)...but again, that can be iffy. I've always had frogs with my bettas with minimal issues unless there's a veiltail betta in the mix(the frogs may bite the tail, but they tend to leave the shorter finned bettas be, same with crowntails but crowntails can be extra aggressive). It's purely on the bettas temperament, and those are always iffy. =P
