The purpose of this article is to describe and illustrate
angelfish having various mutant genes in addition to the gene
for marble or the gene for stripeless. Also, inheritance of
veiltail will be discussed.
These combinations of stripeless have been covered in
previous articles of this series:
1 dose of stripeless + 1 dose of zebra (Part 3).
1 dose of stripeless + 1 dose of dark (Part 4).
2 doses of stripeless + 1 dose of dark (Part 4).
2 doses of stripeless + 2 doses of dark (Part 4).

An angelfish with one dose of stripeless and one dose of
marble has the marble pattern (Figure 1). A blushing marble (two
doses of stripeless and one dose of marble) has the marble
pattern and the red gills show in the juvenile (Figure 2). The
adult blushing marble (Figure 3) has a dull (not shiny) body
with iridescent areas, including over the gills, which masks the
red color of the gills. A blushing marble having two doses of
marble (Figure 4) has more extensive black areas than in a
blushing marble with only one dose of marble, just as a
double-dose marble (front cover) has more black than in a
single-dose marble. The double-dose marble blushing grows slowly
and is frail.

Adding one dose of stripeless to smokey decreases somewhat
the extent of the smokey pattern (Figure 5). The smokey pattern
also is diminished in a blushing smokey (Figure 6), which has
two doses of stripeless and one dose of smokey. The juvenile
blushing smokey has red gills showing, but the adult (Figure 7)
does not show red gills because iridescent tissue has developed
in the gill plates as well as in patches on the body and fins.

In 1977 I obtained new gold blushing angelfish by first
crossing new gold angelfish with a blushing and then by crossing
the offspring brother to sister. New gold blushing, having two
doses of new gold and two doses of stripeless, breeds true. The
new gold blushing angelfish has red gill areas in the juvenile
(Figure 8) but not in the adult. It differs from the blushing
angelfish by lacking black dorsal and anal fins and a black
vertical stripe below the eye. While the new gold blushing has
no black fins or markings, it does have black pigment in the
eye; it also has gold color, especially on the upper part of the
body, in the juvenile.

The adult new gold blushing angelfish is white with pink
tinges, especially along the edge of the body at the base of the
dorsal fin (Figure 9).
Imported new gold blushing (white) angelfish, some with and some
without an orange area on top of the head, were available in
some aquarium shops and by mail order from Golden State Aquatics
about five years ago, but I have not seen them for sale during
the past few years. This year white angelfish were described and
illustrated (Fishman), and were offered for sale by mail order.

In 1974 I obtained Hong Kong gold blushing angelfish by
crossing a Hong Kong gold with a blushing and then by crossing
their offspring brother to sister. The Hong Kong gold blushing
(Figure 10) also is white but its iridescent areas are metallic
gold colored. The iridescent patches on a new gold blushing are
shiny, silvery white.
The previously covered marble combinations are:
1 dose of marble + 1 dose of zebra (Part 4).
1 dose of marble + 1 dose of dark (Part 3).
1 dose of marble + 1 dose of stripeless (above).
1 dose of marble + 2 doses of stripeless (above).
2 doses of marble + 2 doses of stripeless (above).
1 dose of marble + 1 dose of new gold (Part 3).

Adding smokey to marble produces only subtle differences in
the marble pattern (Figure 11). Therefore, a marble angelfish
could also have smokey without your noticing it unless you are
looking for one or more of these smokey characteristics:
black-tipped dorsal fin, black mouth, black in most of the outer
part of the tail. In a marble angelfish without smokey, there
are white streaks extending to the ends of the dorsal and caudal
fins.

Veiltail in angelfish is due to an autosomal (not on a sex
chromosome) dominant gene (Sterba). A double dose of the gene
for veiltail results in a very long, droopy tail (Figure 12).
The double-dose veiltail is smaller and less vigorous than the
single-dose veiltail (Figure 11) and is not a prolific breeder.
A mating in which both parents are single-dose veiltail is
unsatisfactory because this produces 25% normal, 50% single-dose
veiltail, and 25% double-dose veiltail. You need to sort three
kinds of fish and also the double-dose veiltails are
slow-growing and not as attractive as the single-dose veiltails.
It is better to obtain veiltails from a cross of a single-dose
veiltail x normal, which will produce 50% single-dose veiltail
and 50% normal offspring.
