Telescope goldfish are social fish that will scavenge leftover food in the tank. These peaceful fish are suitable for a community tank.
Telescope goldfish fish are friendly and do not have territorial or aggressive tendencies. Stressed fish will dart around the tank or crash into plants and accessories. Changes in goldfish swimming habits indicate illness or distress.
These fish swim all over the tank. Goldfish rarely hover in one place or gather at the bottom of the tank. They will hide amongst plants and accessories when the fish feels threatened.
