Goldfish- Ranchu & Pearlscale

This goldfish wont the 1st prize under the Ranchu category. Nice face!

They are many varieties of goldfishes. It can considered the most wide variety in the ornamental fishes with different cross breeding. Goldfish can breed with any goldfish making them coming in different sizes, characteristics and colours. Talk about "rojak" (mixed fruits) The types of golfishes are namely the ones below:
1. Single tail with dorsal fin
  • Common goldfish
  • Comet goldfish
  • Shubunkin
2. Double tail with dorsal fin
  • Fantail
  • Ryukin
  • Pearlscale
  • Veiltail
  • Telescope Eye
  • Oranda
3. Double tail without dorsal fin
  • Lionhead
  • Ranchu
  • Bubble Eye
  • Celestial
The pictures are on ranchus and pearscale. Ranchu is basically a goldfish without dorsal fin. It is sometimes confused with lionhead. Ranchu can be recognized by the 45 degree slant from the body till tail. Pearlscale on the other hands are recognized by their scales sticking out of the body and normally they are oval or round in shape.
As one of my "sifu" (master) told me the pearlscale is considered one of the most sensitive fish in the all of the goldfishes. They are hard to keep and needs special attentions compared to other fishes. Therefore it is best to keep pearlscale alone and not mixed with other variety of fishes.
Some tips of rearing pearscales:

Ranchu drinking water from the surface

1. Keep the water level low: max 5 inch of water. This is because of water pressure. Even in farms the water is the most at 12cm.
2. Do not use power filter may it be canister, Hang on Back (HOB), Hang on Top (HOT). Normal air bubbles is enough or some simple air powered filter. This is meant to condition the shape of the fish. Too much water movement will make the fish oval.
3. Always monitor the pH. The best is around pH7.5. Something lower than 7 might caused the fish to die.
4. Feed sparingly. Do not overfeed or feed food with too much of protein content. Over 40% protein is not recommended. These fishes are prone to swimbladder disease.
5. Change water constantly. With a simple filter or no filter it is best to do partial water changes once in 3-4 days.

These are some of the basics and normally the pearscale will grow to a very beautiful shape. I am still experimenting with some of the goldfish foods on the pearlscale and I hope to give an update soon.

The 1st prize winner for the pearlscale in Aquafair 2006. This is a local breed "ping pong" pearlscale which makes Malaysia famous.
