General Description
Cleaner Wrasses, belonging to the Labroides genus, are known for removing parasites from fish, although they have preferences for specific types of parasites. They do not typically target marine ich. In aquariums, Labroides dimidiatus are the easiest to keep as they readily accept frozen food, particularly if initially offered live food. It is common for Cleaner Wrasses to be maintained in pairs or alone, but having two males together can result in aggression leading to one's demise. Gender identification can be challenging, so acquiring these fish at a young age is advisable if seeking to pair them. They have a unique sleeping behavior of enveloping themselves in a mucous cocoon amid rocks. While predatory fish seldom prey on them in the wild, the same protection does not always extend to captive settings.
Aquarium Suitability
Cleaner Wrasses are deemed suitable for aquariums, albeit with careful attention. They may display fastidious eating habits, making it challenging to ensure they consume adequate food in captivity. Introducing a varied diet and potentially live food can facilitate their acclimatization.
Care and Hardiness
With an average hardiness level, Cleaner Wrasses require frequent feeding, especially upon introduction to a new tank. To mitigate stress, it is recommended to provide a diet resembling their natural food sources. Additionally, they may change gender from female to male and benefit from being introduced as a pair simultaneously.
Reef Suitability
Cleaner Wrasses are considered reef-safe and contribute to maintaining fish free of parasites. While they may not entirely eradicate severe infestations like marine ich, they are effective in parasite control. However, constant cleaning behavior can stress fish and must be considered when adding them to a tank.
Aquarium Setup
To accommodate Cleaner Wrasses, a tank of at least 500 liters is required. Water parameters should be maintained within specific ranges: KH 8-12, pH 8.1-8.4, specific gravity 1.020-1.025, and a temperature between 22.2-25.6°C. Ensuring the provision of suitable hiding spots among rocks is essential for their well-being.
Behaviour
Generally peaceful, Cleaner Wrasses can exhibit aggression towards similar species of the same gender. They have distinctive sleeping habits and may form pairs or live solo in aquariums, requiring careful monitoring to prevent conflicts.
Feeding and Diet
Their diet primarily consists of parasites, small crustaceans like krill and artemia, and zooplankton such as cyclops and pods. Offering live food enhances their chances of adaptation in a tank and supports their nutritional needs.
Habitat and Distribution
Cleaner Wrasses are found in the Indo-Pacific region, ranging from the Red Sea and East Africa to various islands in the Pacific Ocean. They inhabit reef environments and play a crucial role in parasite control within marine ecosystems. Additionally, these fish can be bred in captivity, promoting sustainable practices within the aquarium trade.
