Origin
Hemichromis letourneuxi is native to tropical Africa. African jewelfish were introduced to the United States possibly as intentionally released or escaped aquarium pets and fish farms.
Life Cycle
It is hard to discern H. letourneuxi from other species due to high variations in coloration and small morphological differences. African jewelfish are approximately 4.7 in. (12 cm) in length. In native populations, it is suggested that H. letourneuxi reproduction occurs during the flooding season (Bailey, 1994). Monogamous with strong parental care, female H. spp. lay a line of up to 600 eggs and the males fertilize afterward. Males defend the spawning site while females tend the eggs. Eggs hatch approximately 72 hours after being laid.
Distribution
H. letourneuxi is found throughout southern Florida and is spreading westward and northward.
Control Efforts
H. letourneuxi may compete with native sunfish for spawning habitat.
