Which of these three fish, the horse-carving, the jade-faced crown and the Texas leopard, are more beautiful and easier to raise. My fish tank is empty and I want to get some of these fish. If anyone has any opinions, please tell me. It would be best if you can explain in detail the breeding environment, breeding temperature, feeding and other details. One is that I use filter cotton, biochemical cotton, activated carbon, ceramic rings, and bacteria houses in my aluminum fish tank. The order is also arranged in this way. I have a bottom filter fish tank. Is there any problem with this arrangement? Some people say that activated carbon cannot be used because it will kill fish and damage the water quality and the overall digestive system? Is this true? By the way, can the three fish, the jade-faced crown, the Texas leopard, and the silver dragon, be raised together in groups? How many horse-carving fish can be raised? I only have an aquarium of 1.2 meters
