Hi knowledgeable people- my 11yo daughter wants to breed some fish. She has spent a month cycling her tank, learning about the plants, carefully testing the water, and I'd like it to be a positive experience for her. I was thinking livebearer/pretty guppies because of the likely success rate, but we'd be lucky to find anyone to take excess offspring, even as feeders, right? She'd prefer that the fry not be feeders (because childhood). Celestial pearl danios maybe? Any other small fish that are somewhat easy to breed and grow out to a decent stage to give away/sell? Thanks!
