A danio is bred by using a low water level in a long tank with a coarse pebbles or even a kid's glass marbles as the substrate. When in breeding condition, danios will chase each other up and down the length of the tank with the females scattering eggs and the males fertilizing them. Without a proper bottom cover where the eggs can fall out of reach, the fish will then go right back and eat any eggs that they can find. Instead, if you allow the fish to breed and then remove them to another tank, many of the eggs will hatch out and become very small free swimming fry in a fairly short time.
