I've kept shrimp in higher flow, & as long as there are areas they can escape to, sometimes they liked to play in the current. Pygmy or habrosus corys are a great idea! Pygmies are more mid-water swimmers, habbies bottom fish, both very cute! My CPDs were very shy as were my rosy loaches, I was disappointed with both when I eventually got to keep them. They were both on the "new & unusual" fish list back in the day...wild caught I'm sure, but maybe not these days...
So FL, how big is your filter that you consider it "high flow"? It can be broken up with plants or hardscape...filters are often "overrated" as far as flow rate goes...
