I was thinking maybe 15 or even 20 as I find behavior is so interesting when you can keep large groups of fish. I just decided since I haven't had them for years and I don't have much in the way of red fish that I'd get some again. But I do have some more pricey plants that I don't want anyone nibbling on. I do add blanched zucchini every other day hung on a couple veggie clips so the BNP, Whiptail cats, and Angels can munch on so maybe they will enjoy that too!
