General: Skeleton Koi are primarily black, with a unique skeletal shaped pattern running the length of their dorsal half. Other colors include various shades of white, yellow, and orange. Most of the shipments Aquatics Unlimited receives will be scaleless. These elegantly-finned fish can live in captivity for 200 years.

Fecundity (Reproduction): Although female Koi may lay up to 100,000 eggs per clutch, many of them will not survive. Naturally, many of the eggs may fall victim to disease or even be consumed by the parents themselves. The rising temperatures of late Spring will trigger spawning behaviors, assuming the Koi have reached full maturity. After reproduction has occurred, locate or remove any piece of spawning material (plants, wood) the eggs have been laid on. Transfer the fertilized eggs to a separate tank with plenty of dissolved oxygen and maintain the same water temperature. Be sure to do very frequent (once per day), yet minor (10 percent) water changes for the first week. After three to seven days, the Koi fry will have hatched. Make sure to keep up with water changes and maintain great overall water chemistry.

Preferred Water Chemistry: Superior filtration, aeration, and plants can be viewed as essential to the pond hobby. Not only does filtration help remove harmful chemicals from the water, it also helps dissolve oxygen into the water column. A water pump, or even waterfall, can help do the same. A stagnant pond traps contaminants and fails to provide a safe living environment for some aquatic life. Help provide fish with shade and dissolved oxygen by adding live plants to any pond.
