Black Ghost
and Hybrid Black Ghost
Multiple Locus Phenotype
Non-wild
alleles that interact to form these phenotypes:
Dark (D), Stripeless
(S)

Ghost is a
term used to describe an angelfish with one stripeless allele. A black
ghost angelfish is a black lace, or double dark black angelfish with one
allele for stripeless. The stripeless allele suppresses the expression
of any underlying body stripes. Possible genotypes for a black ghost are:
D/+ - S/+
D/D S/+
A hybrid
black angelfish with one stripeless allele is generally called a hybrid
black ghost. The most common hybrid black ghost will have the dark allele
paired with a gold allele, but it can also be paired with a gold marble or
marble allele. Possible genotypes for a hybrid black ghost angelfish are:
D/g S/+
D/Gm S/+
D/M S/+
Each of these
genotypes results actually has a somewhat different phenotypic expression,
but they are categorized on this page as simply black ghost and hybrid
black ghost because of common usage of these names. The differences are
described below.
BLACK GHOST:
(D/+ - S/+)

When a black
lace is used as the basis for the black ghost the result is the lightest
colored of the black ghost varieties. The dark color is intermediate in
expression, more of a charcoal gray instead of black. The stripeless
allele prevents the expression of the body stripes, but this phenotype
will typically have a dark stripe through the eye and a dark spot on the
caudal peduncle.
BLACK GHOST:
(D/D - S/+)

When a double
dark black angelfish is used as the basis for black ghost the result is
the darkest of the black ghost varieties. The darker stripe through the
eye and the spot at the caudal peduncle will be present, but may be hidden
by the dark color of the angelfish except under a bright light.
HYBRID BLACK
GHOST: D/M-S/+, D/Gm-S/+, D/g-S/+
The hybrid
black ghost appears black, although not quite as deep a black at the
double dark black ghost. The most popular hybrid black ghost pairs the
dark allele with a gold allele (D/g-S/+). Under a bright light, a stripe
may be seen over the eye and a dark spot at the caudal peduncle. When
gold marble or marble are paired with the dark allele, a bright light will
reveal the darker marbled pattern underlying the overall black coloration.
