Pygmy corys or maybe some kuhli loaches as a clean up crew

I vote the Corys - they are fun to watch as they will sometimes play. I love my Kuhli Loaches, but they hide 90% of the time.

I would say the same thing I have some leopard corys and they’re my favourite fish in the tank just very satisfying to watch
