Types of Angelfish - Different Strains

Domestic angelfish have been bred and crossbred for several decades. There are hundreds of mutations of little importance by themselves.

Silver

The most commonly pictured form, this is also referred to as "wild-type", this type of fish does not contain any dominant color genes and at most a single dose of any recessive genes. Has silver body with 4 vertical black stripes. The stripes will fade and darken with mood. (Under stress will fade, darkest when breeding).

Gold

One of the hardiest and most attractive strains. Some will develop an intense orange crown. Gold is a recessive trait, like blue eyes in humans

Zebra

A Silver with extra stripes. A very popular strain.

Black Lace/Zebra Lace

A Silver or Zebra with one copy of the Dark gene. This results in very attractive lacing in the fins. Considered by some to the most attractive of all angelfish varieties.

Smokey

A variety with a dark brownish grey back half and dark dorsal and anal fins.

Chocolate

Homozygous for Smokey with more of the dark pattern. Sometimes only the head is silver.

Halfblack

Silver with a black rear portion. Halfblack can express along with some other color genes, but not all. The pattern may not develop or express if the fish are in stressful conditions.

Sunset Blushing Veil Angelfish - P. scalareSunset Blushing

The Sunset Blushing has two doses of gold and two doses of Stripeless. The upper half of the fish exhibits orange on the good ones. The body is mostly white in color, fins are clear. The amount of orange showing on the fish can vary. On some the body is a pinkish or tangerine color. The term blushing comes from the clear gill plates found on juveniles. You can see the pinkish gill underneath.

Koi Angelfish - P. scalareKoi

The Koi has a double or single dose of Gold Marble with a double dose of Stripeless. They express a variable amount of orange that varies with stress levels. The black marbling varies from 5%-40% coverage.

Leopard

The leopard is a very popular fish when young, having spots over most of their body. Most of these spots grow closer together as an adult so it looks like a chocolate with dots on it. (Smokey x Zebra)

Blue Blushing

This is a wild-type angelfish that has two Stripeless genes. The body is actually grey with a bluish tint under the right light spectrum. An iridescent pigment develops as they age. This iridescence usually appears blue under most lighting.

Silver Gold Marble

A Silver angel with a single Gold Marble gene. This is a co-dominant expression of Silver and Gold Marble, so you see traits of both.

Ghost

A fish that is heterozygous for Stripeless. This results in a mostly silver fish with just a stripe through the eye and tail. Sometimes portions of the body stripes will express.

Gold Marble

A gold angel with black marbling. Depending on whether the Gold Marble is single or double dose, the marbling will range from 5% to 40% coverage.

Marble Angelfish - P. scalareMarble

Marble expresses with much more black pattern than Gold Marble does. The marbling varies from 50% to 95%.

Black Hybrid

Cross a black with a gold, and you get black hybrids. A very vigorous black, that may look brassy when young. Does not breed true.

Gold Pearlscale Angelfish - P. scalarePearlscale

Pearlscale is a scale mutation. The scale have a wrinkled, wavy look that reflect light to create a sparkling effect. Pearl develops slowly, starting at around 9 weeks of age. In can be inhibited by stressful conditions. It is recessive, requiring both parents to contain the allele. It looks best on light colored fish like Gold, Gold Marble, Albino, Silver and Zebra. It's difficult to see on dark fish and blushing angelfish.

Black Ghost

Same description as a Ghost, with a darker appearance due to the Dark gene. Very similar to a Black Lace without complete stripes. Ghosts generally have more iridescence than non-ghosts.

Albino

Albino removes dark pigments in most varieties. Some, like Albino Marble will still have a little black remaining on a percentage of the fish. The eye pupils are pink as in all albino animals. The surrounding iris can be red or yellow depending on the variety of Albino.
