Pond Boss Forums STOCKING A NEW POND Types of fish to choose Project for my 4 year old

I would not be surprised if you have noticeable inter-species aggression between the Lepomis at densities that would not be a problem for single-species groups. Perhaps you could start with small BG caught from any local water and see how they do in the aquarium under your son's care. Just plain BG in a small aquarium still fascinates my 11 year old (and me too).
