The Praecox Rainbow Fish or Melanotaenia praecox is a very easy to care for tropical freshwater fish. Also known as the Dwarf Neon Rainbow, Dwarf Blue Rainbowfish, Diamond Rainbowfish, and Peacock Rainbowfish, it is a schooling fish that is quite peaceful and is small at only 3" in maximum length. The Praecox Rainbow fish has very large eyes and is normally blue with red if a male and yellow if a female along its top and bottom. This fish is an omnivore and can be fed a variety of flakes, frozen, and live foods. Water temperatures of 64-72° F and PH Level of 5.8-6.5 is recommended. The Praecox Rainbow fish becomes very active when feeding so be careful, they have even been known to jump right out of tanks when going for the food! Make sure you have the lid tightly secured to avoid this problem. Other than that a larger tank is best suitable for this type of fish. Also floating plants and other hiding places are recommended.
