Saw a Jardini Aro for sale at LFS today, was interested in buying but it was sitting on the bottom of the tank. The sales person said this is common behaviour. I know my Silver is never stationary at the bottom of the tank the only time i see him down there is if he follows a rosy red. From what i understand aro's tend to stay close to the surface. Anyways i thought i would ask the experts before i spent 60 plus dollars on this fish.
