    Rhynchocinetes durbanensis

    Camel shrimp

    Indo-Pacific camel shrimp, striped red and white and dotted with white ocelli, with a movable upturned rostrum. It lives in groups of dozens in crevices; in the aquarium it may nip colonial anemones, disc anemones and leather corals.

    Care

    Acclimation: like all shrimp, it copes badly with sudden changes in temperature, pH or other water parameters. Drip-acclimate it for about one hour.

    Setup: provide crevices, overhangs and coral rubble where the group can gather, and enough hiding places for moulting.

    Tankmates: keep it in a group, as solitary individuals often do poorly; keep only one male per tank, as males spar. It usually tolerates other shrimp. Corals: it may nip colonial anemones, disc anemones and leather corals; Rhynchocinetes in general may also go for zoanthids and possibly other soft corals. It usually leaves bubble corals and stinging anemones alone.

    Sensitivities: like other invertebrates, it does not tolerate copper or high nitrate.

    Water: LiveAquaria gives a range of 18 to 25 °C, a specific gravity of 1.023 to 1.025, pH 8.1 to 8.4 and 8 to 12 dKH.

    Feeding

    In the wild it feeds at night on detritus and sessile invertebrates, and is thought to scavenge the leftovers of moray eels.

    In the aquarium it accepts brine shrimp, frozen or freeze-dried plankton and flakes. None of the sources consulted gives a feeding frequency.

    Decor

    • Crevices, overhangs and coral rubble for the group
    • Hiding places for moulting
    • No soft corals or disc anemones to protect

    Tank mates

    Compatibility

    Goes well with

    • ✓Its own kind, in a group (one male)
    • ✓Other shrimp: usually tolerated
    • ✓Bubble corals and stinging anemones: usually left alone

    Avoid

    • ✕Colonial anemones, disc anemones (Discosoma) and leather corals: it may nip them
    • ✕Zoanthids and other soft corals: a risk reported for Rhynchocinetes
    • ✕Several males: they spar
    • ✕Copper-based treatments

    In detail

    Description

    Identification: up to 4 cm; large black eyes, a translucent body with red and white lines, many white ocelli and a Y-shaped white mark on the front of the carapace. Its hinged rostrum, usually angled upwards, gives it the name hinge-beak shrimp. Sexual dimorphism is strong: dominant males have a larger first pair of claws. It is often confused with Rhynchocinetes uritai (the two species were separated by Okuno and Takeda in 1992) and resembles R. brucei; it can also be mistaken for the Atlantic peppermint shrimp (Lysmata), which lacks the pointed rostrum.

    In the wild it lives in the Indo-Pacific, in hollows and crevices from 5 to 35 m. It forms groups of dozens, notably at the entrance of moray eel holes, where it is thought to scavenge the eels' leftovers. Like other Rhynchocinetes it is nocturnal and feeds on detritus and sessile invertebrates.

    Reproduction: females carry 267 to 1,764 eggs, which hatch about 9 days after spawning at 29.2 °C and about 18 days below 22 °C. The species is not evaluated by the IUCN and not listed by CITES.
