  • 2. The Clownfish is a type of fish that lives in salt waterhabitats. It have a few ocean predators, but their greatestthreat is humans (Rhyne, et al. 2012). People who catchclownfish and keep them as pets in aquariums are makinga mistake (Timm, et al. 2008, Fish base, 2012). Incaptivity, the clownfish can live 5 years only but in wildthey live about 10 years (Hill & Scott, 2012, Bonin, 2012).Typically very bright, orange fish that have three whitestripes, one at the head, middle and tail (Brainard, 2012).The males tend to be significantly smaller than thefemales. If you look really closely, you may notice thatthere are thin black lines around the white stripes (Ferrari, et al. 2012). Also, the tips of their fins have a thin blackrounded stripe (Shaye, et al. 2012).Introduction:

  • 8. 1. Clown fish are poor swimmers and neverventure far from their host anemone.2. Fascinating ability of the Clown fish to switchsex. This Fact makes this fish even more of a rarity.3. Male take care of the young till they reach sexualmaturity.4. They are generally very peaceful, but may becometerritorial and fight. When they are born.Clown fish facts:
  • 9. Distribution of Clownfish:Figure (2): You can find Clown fish in the these zones. They live inthe Warmer waters of the Pacific Ocean and Indian Ocean. Theyare also found in northwest Australia, southeast Asia, Japan andMalaysia.Source: A. I. M. S., (2012).

  • 12. 1. The spawning season of the clownfish in allyear season, especially warm season.2. The command of the group is usually the largestaggressive male will pair off with the female tobreed. The rest of the males in the area will notbreed with the female.3. During the fertilization if the female diesbecause of hungry. Then the male changes sex.4. They lay their eggs in a save place near theAnemone they live in.Life Cycle of the Clownfish:
