Just wondering how active silver aros are once they get 24" or larger. I saw a couple 30-36" at our local public aquarium they had a tank 25-30' long but really didn't swim much and moved very slow. Is this common for older aros? Mine is 13.5" and never seems to stop swimming.
Thanks for the Imput.
Some pics from the Downtown Aquarium in Denver, Oh the Arapaima gigas in this tank they are awsome and they never stopped moving.
