Broodstock are reared in controlled ponds or tanks. These tanks are often stocked with cleaner fish, Gobiosoma oceanops, as a biological control for any remaining ectoparasites. The broodstock diet includes sardines, squid and formulated feeds, as well as vitamin and mineral supplements. The water temperature is used to control spawning. [5] [7]
During its juvenile phase, this wrasse can behave like a cleaner fish. [8] Like many other wrasses, the yellowhead wrasse is a protogynous hermaphrodite, starting life as a female and later becoming a male, changing sex when it is about 7 cm (2.8 in) long. [9] Mature males are territorial during the breeding season and gather in a lek. A daily ...
Cleaning symbiosis is well-known among marine fish, where some small species of cleaner fish, notably wrasses but also species in other genera, are specialised to feed almost exclusively by cleaning larger fish and other marine animals. Other cleaning symbioses exist between birds and mammals, and in other groups. Cleaning behaviour was first ...
Fish can not groom themselves. Some fish specialise as cleaner fish, and establish cleaning stations where other fish can come to have their parasites nibbled away. The "resident fish doctor and dentist on the reef is the bluestreak cleaner wrasse". [23]
The orange chromide (Pseudetroplus maculatus ; more commonly Etroplus maculatus) is a species of cichlid fish that is endemic to freshwater and brackish streams, lagoons and estuaries in southern India and Sri Lanka. [3] [4] [5] It is also known as pallathi (Malayalam: പള്ളത്തി) in Malayalam.
Its diet comprises sponges and other encrusting organisms, as well as tunicates. They form pairs. The juveniles and adults may act as cleaner fish, cleaning ectoparasites off larger fishes. [2] When frightened, these fish can produce a knocking sound. [4]
The giant oceanic manta ray sometimes visits a cleaning station on a coral reef, where it adopts a near-stationary position for several minutes while cleaner fish consume bits of loose skin and external parasites. Such visits occur most frequently at high tide. [21]
King angelfish are somewhat popular as aquarium fish; however, their large size, specialized diet, and high cost make them comparatively poor pets. They have not bred in captivity and hence can be very difficult to find in most hobby shops, although they are slightly more available through mail order companies. [ 4 ]
