How to Care for Pearlscale Goldfish

Pearlscale goldfish are round-bodied, decorative fish from the carp family. The name stems from the fact that the scales of this goldfish have a hardened, raised area in the center, typically white, which resembles a pearl. Like other varieties of goldfish, pearlscales are fairly easy to care for, but they have some peculiarities that require special attention. Their body shape makes them susceptible to constipation and swim bladder problems, and they may lose their attractive scales if handled roughly. Pearlscale goldfish generally grow to about 4 inches in diameter, so they do best in aquariums that are 10 gallons or larger.

Instructions

    • 1

      Feed the fish daily with about 1/2 tsp. soaked pellets or flakes, or lettuce. After about five minutes, scoop out any uneaten food, as this can decompose and pollute the aquarium. If there is much left over for several days, try decreasing the amount. If all the food is eaten quickly, consider raising the amount slightly.

    • 2

      Change one quarter to one third of the aquarium water each week. Set new water aside for 24 hours or treat it with a dechlorination product before pouring it into the aquarium.

      Observe the fish at least daily for signs of disease or other ill health. If the goldfish seems to have trouble swimming upright, it may have swim bladder disorder, which is a common ailment for this type of goldfish. If this happens, feed the fish frozen peas (thaw first), which will help open up the digestive tract and ease pressure on the swim bladder.
