I'm thinking of getting either yo-yo or chain loaches for my 65gal planted tank. Would they be okay with my rainbow shark.

Should be fine.

I think they would work fine. I would just keep an eye on things because sometimes Red Tail Sharks tend to get territorial with other bottom dwellers. I don't think it would bother the loaches though.

Yoyos will pretty much hold their own as they are a friendly bunch. Remember to get at least three (more is better). Dwarf chain Loaches move like lightening and are all over the tank not just the bottom and as with all loaches more is better.
