They're peaceful fish. I have one. They generally leave everyone alone and go about their own business.
They're really cute to watch when they're munching on a food disc. Hardy buggers, survives almost anything. They sometimes have spurts of energy where they whizz around the tank at an incredible speed! That'll last for a couple of seconds then they go back to being a sloth.
I cant honestly say they'll leave shrimp alone. I've never seen mine eat any, but then again, i only had a couple of shrimp in the same tank with it for 3-4 days.
Hope this helps.
