MOONS OR PLATY PLATYPOECILIA (Mexico)

Color: RED MOON—deep rich red. GOLD MOON—gold body, red dorsal fin, BLUE

MOON—blue body, black crescent at base of caudal. (Black Crescent

may appear on Red and Gold Moons.) BLACK MOON—black body sometimes

with greenish sheen, also found with red heads, (Black Helmet

Moon), GOLD WAGTAIL—Gold body with black fins and black caudal.

RED WAGTAILS—deep red body with black fins and black caudal.

Breeding Habits: Live bearers—15 to 30 young every 6 to 9 weeks.

Breeding habits same as swordtails, except most young moons come

to top. Cross breeding with swordtail common, producing beautiful

hybrids (HELLERI) larger than either parent and assuming color of

male (MOON).

Temperature: 70° to 80° F. Maturity: 4 to 6 months.

Temperament: Very peaceful. Fry must be kept very warm.

SAILFIN: MOLLIENISIA LATIPINNA

(Southern U. S., Northern Mexico)

[Illustration: About one half size]

Color: Male—body olive green, black stitching; large dorsal fin

(sailfin) lavender and orange spotted with black; caudal, orange

and light blue. Female—similar to male but without large dorsal.

Breeding Habits: Live bearers—have 20 to 100 young at irregular

intervals. All Mollienisia are hardy but females must not be moved

to another tank when young are expected. This frequently causes

young to be born prematurely and few will survive. Moving female

or undue excitement at this time may cause death of female.

Provide ample vegetation in tank. Sailfins are not very

cannibalistic but it is always safest to remove fry for several

weeks. Young are ⅜″ long when born.

Temperature: 45° to 85° F. Breed best at 70° F.

Maturity: 9 months.

Temperament: Very peaceful.

In breeding Mollienisia, no two varieties should be kept in the same

tank as they will cross breed. Each variety should be provided with a

separate tank. (This is also true of the moons). Only very careful

intelligent selective breeding has produced the Black Mollienisia,

later the Sailfin Black Molly, and most recently, Black Molly Sailfin

with an orange bordered dorsal.

BLACK MOLLIENISIA:

(Southern U. S.)

[Illustration: average size]

Color: Both male and female coal black.

Breeding Habits: Live bearers—15 to 25 young born at irregular intervals

throughout the year. Young when born are large and black. Turn

gray in a few weeks and then gradually turn black. Female should

never be moved when young are expected—as this usually results in

loss of young and frequently loss of female. (See Sailfin). Young

are fairly safe with parents if ample floating plants are

provided. “Mollies” are algae eaters. Black Mollienisia have been

crossed with Sailfins producing the beautiful BLACK MOLLIENISIA

SAILFIN.

Temperature: 65° to 80° F. Breed best at 75° F.

Maturity: Good male becomes black in about 6 months. Female about 18

months. Breed at 9 months. Males less hardy.

Temperament: Very peaceful.

“Mollies” are heavy eaters, and largely vegetarians. Some algae should

be present.

MEDAKA: (above) ORYZIAS LATIPES

(China)

[Illustration: average size]

Color: Male and female light lemon yellow. Male slim like

Zebra—sometimes called “Golden Danio.” Female—slightly heavier.

Breeding Habits: Egg layers—these interesting and attractive fish are

the easiest of the egg layers to breed. Eggs cluster about anal

region of female like bunch of grapes. Here they are carried for

several hours and later brushed off on plants where they become

attached. Eggs can be easily seen hanging to plants. Fish seldom

bother eggs but it is safest to remove plants containing eggs to

another jar. Fry hatch in 10 to 14 days. Feed fry infusoria. Never

have snails in tank containing fish eggs.

Temperature: 45° to 80° F. Spawn best at 70° F.

Maturity: Mature in about 6 mos.

Temperament: Very peaceful.
