Djibouti Pistol Shrimp (Alpheus djiboutensis) Breeding Guide

Alpheus djiboutensis is a goby-associated snapping shrimp. Females carry eggs and release planktonic larvae, but home-scale larval rearing is not established.

Overview

Alpheus djiboutensis De Man, 1909 is an accepted species of snapping (pistol) shrimp in the family Alpheidae, with a type locality in the Gulf of Aden and records from the Red Sea region. Like other members of the genus, it bears one greatly enlarged claw that produces a loud snap. Several Alpheus species share burrows with gobiid fishes, and this species is kept in reef aquaria for that partnership rather than for breeding.

Symbiosis Biology

In the goby–shrimp association the burrow is built and tended by the shrimp, while the goby acts as a lookout. When both are outside the burrow, the shrimp keeps an antenna in contact with the goby; the goby, which has better vision, signals danger with a characteristic tail flick, and both retreat into the shared burrow.

Spawning & Berried Females

As in other alpheids, the female carries fertilised eggs attached beneath her abdomen until they hatch. Snapping shrimp form pairs and tend to retain the same mate, with males guarding the female around her vulnerable post-moult period.

Larval Care

Alpheid development passes through nauplius, zoea and post-larval stages, with planktonic larvae before settlement. There is no documented protocol from a whitelisted source for rearing this species to settlement under aquarium conditions.
