PD: An elongated species with a flat-back profile. The lower jaw is longer than the upper, and turned up towards the water surface. The eye is large and the dorsal fin is located far back on the body. The back is light brown to olive and the flanks are darker with a greenish iridescence. On the flanks are a series of small black spots that often form a broken line. The belly is yellowish white. At the base of the caudal fin is a dark spot. The fins are otherwise colorless.
SIZE: Females to 9" (23 cm); males to 4" (10 cm)
SS: None
HAB: Central America; inhabits still marshes and lakes from Honduras to Southern Mexico
S: top
TANK: A tank measuring 40" (101 cm) with a capacity of 45-55 gallons is sufficient (170-209 l). The tank should be heavily planted with a partial cover of floating plants. Leave open swimming areas and use a tight-fitting cover. The filter should be strong but create little current.
WATER: pH 6.8-8.2 (7.5), 10-26 dH (15), 77-86°F (25-30°C)
SB: A predatory species that will feed on smaller fish. Keep in a species tank or combine with other large species. Older fish become more aggressive with age. A shy fish that at first hides among plants.
SC: Cichlasomines species, large Xiphophorus sp (over 4.7" or 12 cm in length), Loricarids, Doradids.
FOOD: Live; fish, earthworms, insects, insect larvae, crustaceans; beef heart; occasionally pellets.
SEX: Female is significantly larger and lack the gonopodium of the male.
B: Spawning is easiest with the addition of salt. As many as 120 live young are born. These measure from 0.5" to 1" (1.3-2.5 cm) in length, depending on the size and condition of the female. The female will not each the young, although they should be removed to a rearing tank of their own. The young grow quickly when fed on a diet of Cyclops and Artemia , and frequent partial water changes are administered. The young can later be fed small guppies. The young must be frequently sorted for size so cabalism does not occur.
BP: 4. Breeding is easy in a large species tank.
R: The Pike Livebearer is the only species of the genus Belonesox.
DC: 6. This predatory livebearer is best kept in a species tank. It requires a diet of live foods, and proper water conditions should be maintained.
