Pearlscale Goldfish (Carassius auratus) is a freshwater fish kept by aquarists for community + species-specific freshwater displays. Suitable for keepers with 6-12 months of experience and stable water chemistry.
Where Pearlscale Goldfish comes from
Pearlscale Goldfish (Carassius auratus) is native to specific tropical and subtropical freshwater systems. The captive-bred Pearlscale Goldfish sold at most LFS comes from generations of farmed stock and is generally hardier and better-acclimated to tank conditions than wild-caught equivalents. Wild specimens are occasionally available for keepers chasing original-bloodline coloration or biotope-accurate stocking.
Pearlscale Goldfish tank size and setup
Pearlscale Goldfish requires a minimum of 20 gallons for healthy adults. The minimum is based on the species' adult size (5 inches), territorial range, and behavior pattern. Most Pearlscale Goldfish sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Pearlscale Goldfish setup: tank sized for the adult footprint, HOB or canister filter rated 4-6x tank volume, dechlorinated water, appropriate temperature heater, and stocking-appropriate hardscape and plants.
Use dechlorinator on every water change. Test parameters weekly during cycling, biweekly once stable. Stable consistency beats sliding-scale "ideal" parameters.
What Pearlscale Goldfish eats
Pearlscale Goldfish is a omnivore. Eats a varied diet of pellets, frozen foods, and supplemental greens. Quality flake or pellet (Hikari, New Life Spectrum, Tetra) plus frozen mysis or bloodworms 2-3x weekly produces best color and behavior. Feed Pearlscale Goldfish appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Pearlscale Goldfish tankmates and compatibility
Pearlscale Goldfish works in community tanks with peaceful species in similar size class. Adult-size matters more than purchase-size when planning stocking. Avoid mixing aggressive with passive species.

Pearlscale Goldfish adult size and lifespan
Pearlscale Goldfish reaches 5 inches at adulthood with a captive lifespan of 5-10 years with proper care. Most freshwater species live 3-10 years; larger species (oscars, plecos, knifefish) reach 10-20+ years.
Can you breed Pearlscale Goldfish?
Pearlscale Goldfish can be bred in dedicated breeding tanks with appropriate setup and water-chemistry triggers. Research the species-specific breeding requirements before attempting.
Common Pearlscale Goldfish diseases and problems
Pearlscale Goldfish is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Pearlscale Goldfish for 4 weeks before adding to your display tank. Treat fish in a separate hospital tank to avoid affecting plants and inverts. Most disease outbreaks trace back to poor water quality, chronic stress, or skipped quarantine.
