Not sure what this is but considering it's from Walmart and a sucker fish it's probably some kind of pleco. No species of pleco, that I've heard of, can healthily live in a 10g.
Otos are also ok in a 10g, but they are algae eaters and not bottom feeders. If you have no algae in your tank, I don't recommend you get otos. They need to constantly graze.
