NAGARAJAN'S WEBPAGE FOR BEGINNER'S TROPICAL FISH AQUARIUM PEARL SCALE
Common Name Pearl Scale
Species/genus 
Keeping Pearl scales are extremely popular. They look like Fan tails except they are shorter and fatter like Ryukin. Its back arches high and the dorsal fin begins just forward of the peak of the hunch. The abdomen is much deeper and rounder than any other variety. Caudal fins can sometime develop into flat square veil tails. They are known for their odd looking scales which almost look like round pearls. There is a hard raised area in the centre of each scale and appear whitish giving the appearance of pearls sticking out of the body. The larger the scales the better is the specimen. Good specimens exhibit scales all the way upto dorsal fins. These scales fall off if there is injury or rubbing, when they grow back it appears like normal scale. This defect is not passed on to the fry no matter when this defect occurred. They live from 5 to 10 years long. They need to kept at relatively constant temperature. Given enough room the pearl scale will grow to the size of baseball not including the fins. Good water quality is necessary to keep these fish healthy. These are not very competitive and hence cannot be kept with other varieties. They are not suitable for outdoor ponds.
BreedingSelect a pair of healthy male and female. You can have multiple males and females breed together as a mass. Have a 20 Gallon breeding tank with some plants and a sponge filter which does not produce a very strong water movement. Water level to be not more than 6 inches. Clean conditioned water should be provided. After introducing the male and female condition them with live foods for a week. Then make a 40% water change with cool fresh water. You can add some ice to the water to make it cool before adding it to the tank. The drop in temperature will stimulate the fish to breed. The male chases the female vigorously, but not violently. The female is pushed to a corner and the male shimmies around the female. Eggs and sperm are released and eggs get fertilized. Eggs are colourless and sticky. They normally stick to plants. Parents may eat the eggs so remove them after spawning. Males can be identified by small tubercules near the Gill covers during breeding period. Normally male will be less rounded than female and will chase her around mostly.

Eggs will hatch after 4 or 5 days. Eggs can be spoiled by fungus, spoiled eggs are white milky coloured. So keep the gentle filter action and add a few drops of methylene blue to the water. Fry may need freshly hatched brine shrimp to start with. They grow fast and soon should be able to eat powdered flakes and other vegetable matter. Good quality fry can be obtained only if the parents are strong and healthy.
