Red Tailed Shark tank mates?

[Fenwaybarks]

In my 55 gallon tank i have one 7 inch Uaru with 3 young severums between 2-3 inches. Besides this there are a school of 10 giant danios that have been recently added. Finally, theres my red tailed shark. Im looking for other bottom feeders that will coexists with it. Preferably a school of bottom dwellers that would look nice and be able to handle the aggression of the shark. Any suggestions?

Cory's. I had Cory's with mine and my shark nerves bothered them. Small ones though. I had albino Cory's. Also I had tiger barbs. They loved to hang out with my shark.
