As for stocking, what are the tanks dimensions?
IMO, I would stay with fish under 12''. You could do a single oscar tank, an African cichlid setup, etc. A common pleco can grow 24'' and have a large bioload so they would not make for a good option. Do your research for whatever fish you choose to get.
