REPRODUCTION: Spawning takes place in a cave, shell, or crevice too small for the male to enter. The male will release his milt at the entrance. The female will stay inside fanning the eggs and protecting them while the male guards outside. Typical spawns may number as many as 200 which take more than a week before they hatch and are mature enough to move out on their own.

Longevity: up to 8 years

IUCN Near Threatened                                                                                                                                                                        Excess sediment has its most severe effects on the rocky areas inhabited by Altolamprologus calvus, filling crevices and blanketing its food source. In addition there are rising levels of toxic heavy metals in the lake’s water.
