Reproduction :  Females will group together at the reef and seek for males. The males then begin to court the females, the bigger and stronger males are more likely to be chosen. Males also can reproduce with multiple females in a night. The male and female pair attach at the pelvic fin and swim to the top of the reef where they release the eggs and sperm in a cloud (about 200 eggs). The fertilized eggs take 18-24 hours to hatch into larvae, then after two weeks they settle into the reef.

Trophic Status :  In the wild & in fish tanks they are very picky eaters. They eat mainly small worms, protozoans, and small crustaceans.

Habitat Preferences :  In the wild they can be found in sandy bottoms between reef crests around  Malaysia, Indonesia, the  Philippines, and Australia. But they’ve also become a popular tank fish, so they can be also be found in households around the world.

Enemies & Friends :  Mandarins secrete a mucous from their skin,  which  helps repel predators. Also their bright coloration is taken by  predators  that they may be toxic.  Scorpion fish  are one of their most known predators. Mandarin fish are very skiddish and shy, so they prefer to avoid other fish.

Interests :  

  • Mandarins don’t have scales! Instead they have a thick protective coat of mucous that covers their body which makes them resistant to Ick and other parasites.  
  • Mandarins picky eating habits make them very difficult to handle in fish tank situations.
  • Mandarin fish can range in price from $15 – $100. With shipping and tax being the most expensive part of purchase.
  • Mandarin fishes life spans are four times longer in the wild than captive.

Quotes :  Melissa King  of Ventura, CA “Beautiful and great fish. Will “dance” at night, if you have a mated pair. Must have LOTS of copepods to eat. Consider having a refugium or well stocked sump if you get this fish. Once that little belly starts to look sunken, it may be too late!”

  2. Thanks for this thorough information that you so fabulously displayed! I find it interesting that it finds the food it likes more easily in the wild than in tanks. I’m wondering if the beautiful colors are mainly on the females since size and strength are what make the males attractive.
