Before we can make recommendations you should tell us the size of the tank and what other tankmates it has. Keep in mind that you're really not getting rid of the mess by adding "cleaner fish"--you're simply turning copious amount of algae into copious amounts of poop all over everything. It would be best to simply figure out the source of the algae--which is likely a combination of too much light, and too much nitrates. Try changing more water and keeping your light on for a shorter period of time, definitely no more than eight hours a day. Plants may help too, however oscars tend to tear through most plants, so you'd be limited to hornwort and java moss. If you don't like the mess, then prevention would be the best way of dealing with it. Snails can also be very effective, nerites cannot reproduce very well in freshwater, so you could add a few without worrying about a population explosion.
The above fish looks like an otoclinus--these fish are social and must be kept in groups. They are wild caught and only eat a small range of algae--so even if you have a lot of algae, if you have the wrong kind these fish won't help and will simply starve to death in your tank--that is, if the oscar doesn't just eat them.
