Hi jshockley1 Welcome to Fish Lore

Please check the dates on threads before replying. This one is almost 2 months old. I'm sure the OP has already made their decision based on advice from the above posters.
Rainbow sharks get much to big to be kept in a 10g tank.
IMO, it's very unfair to keep a 5" fish in 10gs. Best to stick to their recommended tank size.
