![]() ![]() Being a temperate species they seldom last long. In the USA, red rock shrimp are sometimes sold to aquarists as ‘peppermint’ shrimps, and they are mistakenly kept in tropical marine tanks (generally 25–26☌). They often share crevices with, and clean California morays (Gymnothorax mordax), but most of their diet is thought to be from scavenging decaying tissue, including dead fish and invertebrates (Herbinson and Larson 2001). In California, red rock shrimp are often found in aggregations of several hundred individuals and there is a small but high value commercial trap fishery, mainly for fishing bait but also for the aquarium trade (Herbinson and Larson 2001). californica will leave their shelter for food and, with patience, can be hand fed. ![]() morelandi are reclusive, rarely leaving their shelter in daylight while L. morelandi are a brighter red than large L. (there are differences in small spines, hairs, and the number of segments on the second modified leg). It has thinner and more uniform red lines than the other two species. It has likely been previously overlooked or mistaken for L. It is widespread in the Indo-West Pacific and was first identified in New Zealand waters (Auckland, Manukau, and Kaipara Harbours) in 2010. The red-striped shrimp, Lysmata vittata is a small species (to about 4 cm TL) found in northern New Zealand waters from the intertidal zone to about 50 metres. They all look similar with a semi-translucent body and red stripes. vittata) are more widespread, and would be great subjects for a dedicated temperate marine aquarium. The three temperate ‘peppermint’ shrimps (Lysmata californica, L. The tropical IndoPacific species, Lysmata trisetacea, is known from the Kermadec Islands and the banded coral shrimp, Stenopus hispidus, is sometimes found in northern New Zealand (Yaldwyn and Webber 2011). New Zealand has two tropical and three temperate cleaner shrimps. If you want to give it a go there is a great book (Kirkendoll, 2008) and several great online resources (e.g. However, raising the young is challenging as they have several delicate larval stages, a long larval period, and losses are often high. Cleaner shrimps often produce fertile eggs in captivity. However, some aquarists find they also like feeding on other anemones, brain corals, LPS corals, and coco worms. Some peppermint shrimps can be effective at controlling pest anemones, in particular Aiptasia spp. The global trade in ornamental cleaner shrimps is mainly comprised of twelve species (8 Lysmata and 4 Stenopus) which, excluding corals, make up about 23% of imported invertebrate specimens worldwide (Wabnitz et al. All Lysmata shrimps that have been studied, first mature as males (they also have undeveloped ovaries) and then become hermaphrodites and can reproduce as both males and females (Baeza et al. However, most species have a relatively long larval period and poor larval survival. This has prompted numerous studies aimed at developing aquaculture protocols for the popular ornamental species (Wabnitz et al. Most ornamental cleaner shrimps are wild caught and there is concern as to the effect of their removal on tropical reef ecosystems. californica, but they do it passively (Rhyne and Lin 2006, Wicksten 2009). Some peppermint shrimp species do clean fish such as moray eels, e.g. Peppermint shrimps often live in groups, are most active at night where they may move to more open areas to feed, and don’t display to fish. Peppermint shrimps have a semi-translucent body with red bands and comprise a number of very similar Lysmata species (e.g., L. ![]() They are territorial, found in pairs or solitary, display to attract clients, often have a cleaning station, are most active during the day, and cleaning makes up a large part of their diet (Rhyne and Lin 2006, Wicksten 2009). grabhami, banded coral ‘shrimp’, Stenopus hispidus) are specialised cleaners. The strikingly patterned and boldly coloured cleaner shrimps that are popular in tropical marine aquaria (e.g., skunk cleaner shrimp, Lysmata amboinensis, fire shrimp, L. However not all cleaning shrimps are created equal. The relationship is thought to be mutually beneficial as the shrimps receive food and sometimes protection (for those species that share a crevice with a moray), and cleaning improves the fish’s health and reduces its stress levels (Vaughan et al. They are found in tropical and warm temperate waters worldwide and get their common name because they clean fish (and sometimes other animals such as lobsters) by removing parasites, debris, fungi, injured or dead tissue - which promotes healing, and food scraps from the mouth (Wicksten 2009). Cleaner shrimps are attractive marine shrimps from the Families Hippolytidae, Palaemonidae, and the shrimp-like Stenopodidae. ![]()
