The bluestreak cleaner wrasse (Labroides dimidiatus) is one of several species of cleaner wrasses found on coral reefs from Eastern Africa and the Red Sea to French Polynesia. Like other cleaner wrasses, it eats parasites and dead tissue off larger fishes' skin in a mutualistic relationship that provides food and protection for the wrasse, and considerable health benefits for the other fishes. It is also notable for having potentially passed the mirror test, though this is not without controversy. Taxonomy A genetic analysis of L. dimidiatus revealed the population fell into two monophyletic clades, with Indian Ocean populations generally having different stripe widths to western Pacific fishes. The Japanese cleaner wrasses, though, fell within the same group as Indian Ocean fish, despite differing in appearance, and both clades overlap around Papua New Guinea.Two closely related cleaner wrasse species, Labroides pectoralis and Labroides bicolor, were grouped inside the L. dimidiatus clade, so the bluestreak cleaner wrasse may in fact be polyphyletic, incorporating several species. Description  This is a small wrasse, averaging 10 cm (3.9 in) long, at most 14 cm (5.5 in). It can be recognized thanks to a wide longitudinal black stripe running along the side and eye; the back and the stomach are white (sometimes slightly yellowish). This white part changes to a bright blue on the front of the animal, while the black band widens at the tail. The young are black with an electric blue line. Distribution The bluestreak cleaner wrasse is found on coral reefs in the tropics from the Red Sea and Indian Ocean to the western Pacific (including Papua New Guinea, Japan, Fiji, and French Polynesia).[5] It was first recorded from the Kermadec Islands Marine Reserve north of New Zealand in 2015, after researchers examined hundreds of hours of unused documentary film footage. Cleaning Cleaner wrasses are usually found at cleaning stations. Cleaning stations are occupied by different units of cleaner wrasses, such as a group of youths, a pair of adults, or a group of females accompanied by a dominant male. When visitors come near the cleaning stations, the cleaner wrasses greet the visitors by performing a dance-like motion in which they move their rear up and down.The visitors are referred to as "clients". Bluestreak cleaner wrasses clean to consume ectoparasites on client fish for food. The bigger fish recognise them as cleaner fish because they have a lateral stripe along the length of their bodies, and by their movement patterns. Cleaner wrasses greet visitors in an effort to secure the food source and cleaning opportunity with the client. Upon recognising the cleaner and successfully soliciting its attention, the client fish adopts a species-specific pose to allow the cleaner access to its body surface, gills and sometimes mouth.[citation needed] Other fish that engage in such cleaning behavior include goby fish (Elacatinus spp.) The bluestreak cleaner wrasse is known to clean balaenopteridae, chondrichthyans, homaridae, octopodidae, and dermochelyidae In different regions, the bluestreak cleaner wrasse displays various degrees of dependency on clients' ectoparasites as a primary food source. In tidal environments such as the Great Barrier Reef, the bluestreak cleaner wrasse is a facultative cleaner that feeds more on corals than on fish clientele.Juvenile bluestreak cleaners are seen to bite their clients more often than the adults within that region, thus changing the dynamic of the known mutualistic relationship.However, in regions where the bluestreak cleaners are solely dependent on clients' parasites, fish who have access to cleaning services have better body condition than those without cleaner access. In the Marsa Bareika of the Ras Mohamed Nature Reserve, Egypt, the bluestreak cleaner wrasse live in specific sectors of the shallow reefs and are shown to rely on ectoparasites from species such as the brown surgeonfish and white belly damselfish. In this region, fish that visit cleaner wrasses have lower antibody responses than those without cleaner access, suggesting that cleaner access may decrease the need for active immunity. Reproduction Cleaner wrasse males defend specific living territories from other males in which they are able to have control over the females in those territories. When the dominant male no longer exists in that territory, one of the larger females is able to change sexes to take control over that territory.

Leptastrea is a genus of stony corals, often described as "encrusting" or "plocoid," meaning they grow in a flat, dome-like shape by covering the substrate. They are relatively beginner-friendly corals, known for their diverse color variations and a tendency towards slower growth compared to some other encrusting corals. Leptastrea colonies typically have small, barrel-shaped corallites with distinct grooves and tubercles.  Key features of Leptastrea corals: Growth Form: Encrusting or plocoid, forming flat or dome-shaped colonies.  Corallites: Small, barrel-shaped corallites with grooves and tubercles separating them.  Color: Available in a wide range of colors, including cream, green, yellow, and variations of these.  Growth Rate: Generally slow-growing, making them suitable for smaller tanks or aquascapes where rapid growth is undesirable.  Lighting: Can tolerate a range of lighting conditions, from lower to moderate.  Current: Often found in areas with moderate to high water movement.  Care: Considered beginner-friendly, but proper feeding (small food particles) and adequate water parameters are important.  Stinging: Leptastrea have a stinging power, so spacing them appropriately from other corals is recommended.

Most commonly found is pure blue, dark blue, or light blue, although observers find the aqua, purple, or orange variation throughout the ocean. These sea stars may grow up to 30 cm (11.8 in) in diameter, with rounded tips at each of the arms; some individuals may bear lighter or darker spots along each of their arms. Individual specimens are typically firm in texture, possessing the slightly tubular, elongated arms common to most of other members of the family Ophidiasteridae, and usually possessing short, yellowish tube feet. An inhabitant of coral reefs and sea grass beds, this species is relatively common and is typically found in sparse density throughout its range. Blue stars live subtidally, or sometimes intertidally, on fine (sand) or hard substrata and move relatively slowly (mean locomotion rate of 8.1 cm/min). The genus Linckia, as is true of other species of starfish, is recognized by scientists as being possessed of remarkable regenerative capabilities, and endowed with powers of defensive autotomy against predators.Although not yet documented, L. laevigata may be able to reproduce asexually. L. laevigata is apparently not an exception to this behavior, as many individuals observed in nature are missing arms or, on occasion, in the comet form. This sea star is fairly popular with marine aquarium hobbyists, where it requires a proper, slow acclimatization before entering the tank system, and an adequate food source similar to that found in its natural habitat. Generally thought of as a detritivore, many sources maintain that this species will indefinitely graze throughout the aquarium for organic films or sedentary, low-growing organisms such as sponges and algae. In the marine aquarium hobby, they have been seen to consume Asterina Starfish, which are commonly introduced into such aquaria on the ubiquitous "live rock" used in such settings.

The Purple Linckia Starfish (Linckia sp., often L. laevigata color morph or Leiaster teres) is a striking echinoderm known for its deep purple coloration, long, slender, cylindrical arms with rounded tips, and sometimes a "fuzzy" or smooth, firm texture. These sea stars are popular in the marine aquarium hobby for their vibrant color and peaceful nature, though they are considered expert-only due to specialized feeding requirements.  Description and Characteristics Coloration: Ranges from deep purple to lavender, often with a velvety, "fuzzy" appearance. Size: Can grow up to 30 cm (11.8 in) in diameter, with aquarium specimens often seen around 8 inches. Arms: Five long, cylindrical arms that are slightly tapered, often appearing like "Play-Doh" models. Tube Feet: Possesses short, bright yellow tube feet used for movement, which contrasts with the purple body. Regeneration: Possesses remarkable regenerative capabilities, able to regenerate a whole new star from a single severed arm.  Habitat and Behavior Range: Found throughout the tropical Indo-Pacific region, inhabiting coral reefs and seagrass beds at depths of 6 to 85 meters. Diet: Primarily a detritivore and scavenger, feeding on bacterial films, sponges, and microorganisms on rocks. Activity: Generally active during the day, moving slowly across rocks and sand.  Aquarium Care Requirements Acclimation: Requires a very slow, long drip acclimation (at least 2.5 to 4 hours) to adjust to new water parameters. Tank Size: Requires large, well-established aquariums (usually 55-100+ gallons) with ample live rock to support their feeding needs. Sensitivity: Very intolerant of sudden changes in salinity, pH, and oxygen levels. They are highly sensitive to copper-based medications. Diet in Captivity: Feeds on established bacteria films and microfauna in the tank; they are difficult to target-feed, making a mature tank essential.
