The young of these fishes develop inside the body of the female until they have absorbed the yolk-sac and are then released. Most livebearing fishes are easily sexed : male fishes have the anal fin modified into a rod-like structure called the gonopodium, through which the fertilizing spermatophores are introduced into the female. Gestation is approximately 3o days and broods may number from 20 to 200. It is possible for the females of some species to deliver successive broods without a repeat mating with the male. (more…)

Guppy; Millions Fish Poecilia(formerly Lebistes) reticu/ata Male 28-32 mm 1-1* in; females 65 mm 21 in. Trinidad : various waters. A well-known species. No two males are ever exactly alike; the females are much larger and do not share the males‘ rainbow colours. Genetic experimentation by hobbyists has resulted in many colours and finnage shapes becoming internationally recognized standards. Several specialist groups exist solely for the Guppy fancier. Serious breeders separate the sexes as soon as they are recognizable to prevent unwanted broods. Temperature: 24^°C (75^°F). Diet: all foods. Breeding: very prolific. Females should be given a separate, well-planted tank in which to give birth. (more…)
