Zebra fish gets its name from the horizontal, blue stripes on its body, resembling that of a zebra. Not only is it a very popular aquarium fish, but is also one of the most widely used model organism in genetic research.
Moving on to Zebra fish breeding, the female fish ready for spawning have a larger abdominal area. Usually a fish is ready for breeding in about six months time. The male and female fishes are kept in separate tanks, typically. The male fishes can be distinguished from the females by their slimmer, more streamlined body.
The tank for breeding should be set with small nets or marbles to prevent the fish from reaching the bottom of the tank. This is because the Zebra fish tend to feed on their own eggs and fry. The net should be set at a height of 15 centimeters from the base. Once this is done, the male and female fishes are dropped into the tank, on top of the net. The eggs are laid by the females and are fertilized by the males. After the eggs are laid and they settle at the bottom of the tank, remove the fishes from the tank. The eggs start to hatch within three days and as the fry grows the zebra line start to appear and becomes prominent on their body.
