The pike topminnow (Belonesox belizanus), more commonly known as pike killifish and sometimes referred to as topminnow,

type locality as Belize, which is reflected in this species' specific name.[7]

Ecology

Unlike most poeciliids (which tend to be generalists or micropredators), this is a highly specialized predator, with an extremely flexible upper jaw that enables it to take very large prey items for its size.[8]

Description

It grows typically to 9.7 cm (3.8 in)

caudal fin.[9] They are also a livebearing fish.[10][3]

In the aquarium

This fish can be found in the aquarium trade, but is not an easy aquarium resident, especially by poeciliid standards.
