Don't kids eventually leave the nest to free up resources? Or these days do they always have to have a place to return to? Maybe they'll have to share your new fish room if they do...A whole new meaning to sleeping with fishes
I kept them for a year or so. They bred often and I was able to sell a few dozen juvies to a local fish store.
They were my best success at breeding unless you count livebearers, lol.
