Florida cooters make attractive additions to aquariums as juveniles, but will reach fairly large size eventually. Pond cooters are good swimmers and can be kept in deep water aquariums; however they are avid baskers and like painted turtles, require a basking site where they can completely extract themselves from the water. Filtration of aquarium water is suggested.
Pond cooters are primarily herbivorous, although juveniles will eat some insects and take chopped meat. Florida cooters will consume most live aquatic vegetation, such as elodea and pondweed, so keep that in mind when considering the addition of a pond cooter to an aquarium setup. In captivity, adult pond cooters seem quite fond of tortoise chow.
