Hemirhamphidae Goodeidae

The Hemirhamphidae (which are false livebear-ers) originate from Asia, where they live in hard, sometimes brackish waters. They are characterized by a lower jaw which projects distinctly further than the upper. The Goodeidae, natives of Mexico, are trtie livebearers. Contrary to what happens with the Poeciliidae, the females produce only one brood after mating.

(Hemirhamphidae)

Dealers offer several species under this name. The Malayan halfbeak proper lives and feeds just below the surface. Breeding is less prolific than with the Poeciliidae. The fry acquire the characteristic "beak" only after several weeks. Size: 7 cm.
