65 Gallon stocking help

[Timed]

Hey, after a while of having an empty 65 gallon tank in my room; I decided to start it up again. The only problem I'm having is deciding how to stock it. I really like the idea of having a large school of tiger barbs but I'm not a trying to do another 1 species tank (had 1 Oscar in the tank before). I was thinking maybe a school of tiger barbs a single red tail shark or a rainbow shark (either or) and some otos. I was wondering if I would run into problems stocking those 3 species together as all sources I find say different things. Also if you have any other ideas for stocking I'm glad to listen an empty tank is like an empty canvas endless possibilities and I would love to hear your ideas.

I had a school of Tiger barbs with a rainbow shark, 2 bala sharks and a blood parrot the only problem with the tiger barbs is that they are very nippy so you definitely can't have any fish with long fins personally I would get tetras because they aren't as aggressive and get along with the rainbow shark
