Large pearlscale goldfish are freshwater fish originating from Japan. They are large, with dark goldish-brown coloration and an elongated, compressed body.
They have a long thin fin for about as long as the rest of the body. Unlike most other goldfish breeds, large pearlscale goldfish will grow much smaller than their tank size and reach up to 3 inches in length.
These fish are referred to as “large” pearlscale goldfish because the body is much larger than other kinds, but their actual size is debatable.
These fish get smaller as they age, yet the shape of their body is determined by the sex and caring of the fish, so they will never achieve a length of more than 2 inches.

Their maximum length ranges from 1 to 3 inches.

Breeding
Large pearlscale goldfish can reproduce both sexually and asexually. Males and females have different characteristics, which is important to know when breeding these fish.
Generally, their eggs are large, and their bodies are small; but this isn’t always true.
Because they have no hump, they cannot produce many eggs at one time; in most cases, this fish will spawn every two months only.
Social Behavior
Large pearlscale goldfish are dull fish, and this may have to do with their breeding habits. They can become very aggressive, and the fighting can be very intense when they do.
They will even attack one another when they aren’t looking. This is why they tend to be solitary; they prefer to stay by themselves and fight their own battles rather than team up with others of their kind.
However, these fish are generally peaceful in human care because of their social nature.
Tank Setup
large pearlscale goldfish prefer hard alkaline water with a pH level of 7.5 to 8.2 and a water hardness level of 20 to 30 dH.
A tank of at least 30 gallons is recommended, although it will be much happier in at least 40 gallons.
A dark gravel or sand substrate is best because the scales on this fish are very reflective and can easily be damaged by sharp objects or rough surfaces.
