Feeding frogs to Arowanas reminds me of living on the pond. My arowanas loved a tree frog snack. There is a creek behind the new house and probably can find some when summer comes around.
I've been considering removing some fish in my tank and making room for a Dorado to make a mostly South American tank. Can they live with Black Arowana, cichlids, South American cats, and a big school of adult red hooks? Or should the Red Hooks go?
