pro tip, do what i did with my cichlid pond and add about 6 convicts in right now. will help you out on the feeding bill and add some diversity, also throw in some daphnia and amphipods, they will show up naturally eventually but i like to speed the process up. most likely anything too big for the dovii to eat will be killed, and obviously anything small enough for them to eat will be killed also, but if you provide a few hides that the convicts can fit in that the dovii cant, they will breed.
