Actually, fish farming is not about fish, but about water, and water can bring you wealth. However, stagnant water has no Feng Shui effect, only living water has the effect. Living water is formed when fish swim. Therefore, raising fish to improve Feng Shui has nothing to do with the species of fish, as long as the fish tank is placed in the right place. Therefore, any fish that can be kept alive can be called Feng Shui fish.
