These fancy goldfish varieties aren't particularly good swimmers. Their form and fins are not the most conducive to fast swimming. So don't expect them to zigzag all over the tank. Even so, you must provide an adequate area for comfort. The Pearlscale goldfish require a tank with a capacity of no less than 10 gallons.

If you can, get a 20-gallon tank instead. That's plenty of room for a single goldfish. For each extra fish, add another 10 gallons to the tank size. This will make sure that the water quality stays consistent and that there's plenty of room for the fish to move around.

Water Conditions

When setting up a tank for your Pearlscale goldfish, you must maintain water temperatures between 65°F and 80°F.

Use a quality aquarium heater to maintain the ideal water temperature. You can also use a submerged thermometer to monitor the water temperature inside the tank.

It's also important to maintain a moderate pH level in the tank. The ideal pH range for Pearlscale goldfish is 6.5 to 7.5. Water hardness should be between 4 and 20 dGH.

You can also add some rocks and driftwood to the tank. These elements not only look good but also provide hiding places for your fish. Just be sure to use only aquarium-safe rocks and driftwood. Most pet stores carry a wide variety of aquarium-safe rocks and driftwood.

You can also add gravel to the bottom of the tank. But avoid using gravel that is too small. The Pearlscale goldfish have a tendency to swallow gravel when they feed. So, be sure to use only aquarium-safe gravel that is too large to be swallowed.

Also, stay away from fast swimmers because they might nip the fins of the Pearlscale goldfish. They are best put with slower swimmers.

Some suitable tank mates for Pearlscale goldfish include other fancy breeds like Black Moor Goldfish, Comet goldfish Veiltails, Bubble Eye Goldfish, and Lion head Goldfish.

Pearlscale Goldfish Breeding

Pearlscale goldfish are not easy to breed in captivity. They require a large tank, good water quality, and a lot of patience. If you're interested in breeding Pearlscale goldfish, here are some things to keep in mind:

  • Choosing the proper pair: It is critical to choose a compatible pair of fish. Make sure you don't pick fish that are closely related. The breeding pair must be at least two years old. They must be of the same size and age. It is always best to select a group of young fish and allow them to choose their own mates.
  • Conditioning the parents: The parents must be in good health and well-conditioned before they can be bred. This means they should be well-fed. Increase the amount of live food in their diet. This will help them build up their energy reserves. Make sure to do regular water changes and maintain good water quality. Increasing the temperature of the tank by a few degrees will also help trigger the spawning instinct.
  • The spawning tank: The spawning tank should be at least 30 gallons. It should have a sponge filter and plenty of hiding places. Aquarium salt can be added to the water to help prevent infections. The water should be between 72-78 degrees Fahrenheit. Make sure to do a water change of 50% before you add the parents.
  • Spawning: The spawning process can take several hours or sometimes several days. In order to trigger the spawning process, it is always best to slowly increase the water temperature from 68-72 degrees Fahrenheit over a period of 10-14 days. The spawning process starts with the male chasing the female. He will then nudge her sides with his snout. The female then will release her eggs, and the male will fertilize them. Once the eggs are fertilized, the parents should be removed from the tank.
  • Pearlscale goldfish fry: The eggs will hatch in 7-10 days. During this time, it is important to maintain good water quality. The parents should be removed from the tank after spawning. The fry will be very small and vulnerable. You don't have to feed them for the first few days as they will live off their yolk sacs. After that, you can start feeding them very small live foods such as baby brine shrimp or daphnia. As they grow, you can gradually increase the size of the food as they require additional calcium and protein at this point in time. Be sure to provide plenty of hiding places for the fry as they will be very susceptible to stress. Do regular water changes and maintain good water quality.

As you can see, breeding Pearlscale goldfish is not for the faint of heart. It requires a lot of patience and dedication. But if you're up for the challenge, it can be a rewarding experience.
