You could have a pair with no problems. I have a pair in a 29 gallon and a trio (one male two females) in a 30 gallon. They are both close to the size of your tank. I suggest you make a decision based on the footprint of the tank. If it's high, go with two but if it's long, go with three.
It's probably best to keep either one male to one female or have two females either alone or with one male.
I'll move your thread over to the Plecos Otos and other Loricariids section.
