WebFish go through various life stages between fertilization and adulthood. The life of a fish start as spawned eggs which hatch into immotile larvae. These larval hatchlings are not yet capable of feeding themselves and carry a yolk sac which provides stored nutrition. WebClownfish and other parentally guarded species spend among the shortest periods of time as larvae — perhaps as little as one to two weeks. One possible reason for this is the larger size of their eggs and the longer period the embryos spend developing inside them. Open water spawners, such as angelfish, usually spend considerably longer as ...
