I think you meant roseline shark which just might eat your shrimp. Also, they are much happier in groups of 3 or more. I have six and they are about 6 inches long. Very nice fish and are relatively peaceful but I know that mine like ghost shrimp which I believe are the same size as cherry shrimp. Good luck
just came home and realized 1 shrimp wasw missing so i moved some plants and rs just like killed him the guy at the lfs said it would have been ok ...he hunted dowen my 4 shrimp...
I'm really sorry to hear that. I'm in US and cherry shrimp are not cheap. Roselines are typically peaceful with other fish. I have 6 and they have never caused any trouble. However, like I said, they love the ghost shrimp that I feed my fire eel and they can be very fast. If you want to keep him, I would suggest you get at least 2 more as they much better in groups.
