Hi there
I have a saltwater aquarium. Recently I discovered 2 objects (not sure what they are) living at the surface of the water (I have live rock in the tank). They are very active in rolling and flipping while remaining relatively in the same area of the surface. I'd describe them as being about 1/8" long, a neutral grey color and they appear to have a tail and possibly some fins. Any ideas on what they are? I don't know whether to get rid of them.
