I have 4. They are a very peaceful fish; a perfect community member. Mine do well on a staple diet of flake food, supplemented with frozen brine shrimp, baby brine shrimp and occasional frozen bloodworm. They will also pick at spirulina tablets. They are an interesting fish, they seem to hover with quick fin movements, I've heard them described as hummingbirds. That's a very good price. I'd scoop them up if they fit in with your tank.
