Barbs, including the green tiger barb, are external free spawners. This means that they do not carry fertilized eggs, but that the eggs are fertilized externally. Females will develop eggs when they are in good condition; meaning good water quality and well fed. Essentially they will carry eggs until they are triggered to spawn. If they are not triggered to spawn, the eggs will often be re-absorbed and used and nourishment.
