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, [13] and by their movement patterns. Cleaner wrasses greet visitors in an effort to secure the food source and cleaning opportunity with the client.
Cleaning stations are a strategy used by some cleaner fish where clients congregate and perform specific movements to attract the attention of the cleaner fish. Cleaning stations are usually associated with unique topological features, such as those seen in coral reefs [ 1 ] and allow a space where cleaners have no risk of predation from larger ...
For freshwater aquaria, gravel is the most common substrate. To prevent damage to fish, gravel should not be sharp. Aquarium gravel can be as coarse as pea-sized or as fine as 1–2 mm. [1] It is available in a number of colors, and may be naturally colored or dyed, and may have a polymer seal to ensure it does not affect water chemistry. [1]
Juvenile A. taeniatus fish match the appearance of juvenile L. dimidiatus (black body, blue dorsal stripe), and continue to match the coloration of cleaner wrasses of the same size throughout growth. [ 5 ] [ 6 ] It is not known whether the false cleanerfish adopts a permanent color pattern or if it alters its coloration to mimic the appearance ...
When a client approaches a cleaning station, they usually open their mouth wide or position their body in such a way as to signal that they wish to be cleaned. The cleaners then remove and eat parasites, dead skin etc. from their skin, even swimming into the mouth and gills of any fish being cleaned. This is a form of cleaning symbiosis.

The freshwater drum prefers clear water, but it is tolerant of turbid and murky water. They prefer the bottom to be clean sand and gravel substrates. [22] The diet of the freshwater drum is generally benthic and composed of macroinvertebrates (mainly aquatic insect larvae and bivalve mussels), as well as small fish in certain ecosystems. [23]
