   The Bluestreak Cleaner Wrasse or Common Cleaner Wrasse is one of the most fascinating and well-known saltwater fish.

   When talking about a cleaner wrasse, the Common Cleaner Wrasse or Bluestreak Cleaner Wrasse is the fish that is generally being referred to. Though there are actually five species of Labroides, the Bluestreak Cleaner Wrasse is the best known. It has the widest natural distribution in the tropical Indo-Pacific of these cleaners, it has been the focus of most research studies, and it is the species most commonly seen in fish stores.

   The Bluestreak Cleaner Wrasses will form a symbiotic relationship with the other reef fish by cleaning them of unwanted parasites. Cleaner Wrasses are peaceful attractive fish with a most intriguing "dance" that they perform to solicit clients (other fish) and to calm them, allowing the cleaners to remove parasites and other debris from their clients bodies, fins, and mouths. They often set up a "cleaning station", an area where the other fish can visit just for this beneficial service. Often times the fish can be seen inside the mouth of much larger fish cleaning away!


Dr. Jungle says, "Cleaner Wrasses are no longer
recommended for the average marine aquarium."

Not a Pet!As recently as the mid 1990's, the Cleaner Wrasses were regarded as a beneficial addition to the marine hobbyist's aquarium. Tens of thousands of these little fish have been brought into the industry. Out of those, there is just a sprinkling of reports describing any sort of success in keeping this fish alive. With the increased knowledge of their specialized requirements, and the extreme difficulty of sustaining them in captivity, cleaner wrasses are no longer recommended for the home marine aquarium.

   Like all the cleaner wrasses, the Bluestreak Cleaner Wrasse's sustainability in captivity is dismal, even though it is the best survivor in this group of wrasses. Fortunately there are a variety of other marine species you can choose from that perform beneficial cleaning services for other fish. These other cleaners are readily available and sustainable. The two main groups of cleaner fish are the gobies (genera gobiosoma especially) and wrasses. Some juvenile species of angelfish will also perform cleaning services. Another intriguing alternative is the cleaner shrimps, such as species of the genera Lysmata and genera Periclimenes.

Cleaner wrasses are very helpful in the wild. They perform a service to other reef fish by cleaning them of unwanted parasites, and that in turn provides them with food. As the local dermatologist they often will set up a "cleaning station" and have a large client base. Although this wrasse is reef safe, it is very difficult to keep. Sometimes you can get them to eat prepared foods in the aquarium, but there is something they get in the wild that we have yet to provide for a long life in captivity.

Habitat: Distribution / Background

   The Common Cleaner Wrasse or Bluestreak Cleaner Wrasse is found in the Indo-Pacific from the Red Sea to the Line, the Marquesas, and Ducie Islands, Japan, and Lord Hoe and Rapa Islands. They are found at depths of 1 to 30 meters (3.28 to - 98 feet). It inhabits all reef areas of inner lagoons, reef terraces, and outer reefs.

  • Scientific Name: Labroides dimidiatus
  • IUCN Red List: NE - Not Evaluated or not listed - These fish are not listed on the IUCN Red List.


   The Bluestreak Cleaner Wrasse or Common Cleaner Wrasse is a small fish with a slender elongated body. The body is separated by a large black horizontal band with white on the underside and generally blue on the upper half, though fish from deeper water will often have a yellow back.

  • Size of fish - inches: 5.5 inches (13.97 cm) - Bluestreak Cleaner Wrasse adults reach up to about 5.5 inches (14 cm).

Fish Keeping Difficulty

   Very difficult. Though reef safe and peaceful the Bluestreak Cleaner Wrasse is only for advanced to expert aquarists. Out of all the Labroides this cleaner has the best survivability record, still many will last only a couple of weeks to a month before dying from malnutrition even if they are feeding on prepared foods.
   Unlike 'facultative' cleaners such as cleaner gobies and cleaner shrimp, cleaner wrasses are 'obligate' feeders. Facultative cleaners engage in removing parasites from other fish but this in not their primary diet. For 'obligate' cleaners such as these wrasses, the cleaning activity provides them with their primary source of food. Most of the Labroides will accept prepared foods, but still starve due to malnutrition.

  • Aquarium Hardiness: Difficult to Impossible
  • Aquarist Experience Level: Advanced

Foods and Feeding

   The Bluestreak Cleaner Wrasses are carnivorous. Just as their name describes, they are cleaner fish whose entire lifestyle consists of (and relies on) a symbiotic relationship with other fish.They are classified as obligatory feeders, meaning they obtain all or virtually all of their nutrition by consuming parasites dead tissues, mucus, and other debris from the bodies, fins, and mouths of other fish.
   Ideally cleaner wrasses could be kept in a reef environment supporting a large and diverse population of fish along with a variety of ectoparasites, basically supplying enough natural foods to sustain the cleaners.
   In less than an ideal environment, trying foods similar to their natural diet such things as Cyclopeeze or daphnia would be highly recommended. Also encouraging them to take other finely chopped meaty foods such as shrimp, brine shrimp, squid, clams, and even chopped beef heart has said to be successful. In the wild they feed constantly while performing their normal cleaning activities, in the aquarium they should be fed several times a day. Very few have been successfully encouraged to eat other foods.
   Even with these efforts survivability is questionable. Most of the time these fish will seem like they are doing fine eating prepared foods, only to slowly die from malnutrition.The Bluestreak Cleaner Wrasse L. dimidiatus is the cleaner most often reported as being kept with any success, and it too is very minimal.

Aquarium Care

   The few reports of successfully keeping any cleaner wrasses indicate that they are hardy once acclimated and if kept in quality water conditions. These are cleaners that have survived the stress of importation and relocation, and are eating prepared foods.
   They will sleep in holes in the rock or reef, or burrow into the substrate. Basic marine aquarium maintenance includes frequent water changes.
   For more information see, Marine Aquarium Basics: Maintenance

Aquarium Setup

   This fish likes to have plenty of live rock for hiding and for stationing their "cleaning posts", along with a lot of fish to clean. Provide a sandy substrate, though they may sleep in holes in the rock or reef, they often burrow into the substrate at night. They also have a tendency to jump from the aquarium, so keep it tightly covered.

Water Region: Top, Middle, Bottom
   They will spend time in all parts of the aquarium. If two of these wrasses are kept together they may establish a cleaning station, while those kept singly will tend not to do this in captivity.

  • Minimum Tank Size: 20 gal (76 L) - A minimum 20 gallon (78 liters) aquarium, though 55 gallon (208 liters) is preferable.
  • Substrate Type: Any
  • Lighting Needs: Moderate - normal lighting - Prefer sunlight, though these fish are diurnal and sleep when it gets dark.
  • Temperature: 74.0 to 79.0° F (23.3 to 26.1° C)
  • Water Movement: Any
  • Water Region: All - They will spend time in all parts of the aquarium. If two of these wrasses are kept together they may establish a cleaning station, while those kept singly will tend not to do this in captivity.

Social Behaviors

   The Bluestreak Cleaner Wrasses live singly or in groups. As adults some become solitary and territorial. In the wild a cleaning station will have either a pair of adults, a group of juveniles, or a group of females with one dominant male. They will form pairs in the aquarium but it is hard to tell sexes so several different sized fish should be placed together to avoid problems.
   All cleaner wrasses are peaceful and beneficial in keeping other fish parasite free. Labroides have a symbiotic relationship with other fish who provide them with nutrition. In return for their services they are even afforded a certain degree of protection from the natural predatory inclinations of larger fish which instead become their hosts. Some of the Labroides even clean large moray eels! Fish will come to the "cleaning" station on a regular basis to be cleaned.
   Research the type of fish this cleaner regularly cleans before adding to the tank to be sure a larger fish doesn't eat the cleaner wrasse due to not recognizing it. Though most fish recognize cleaners, large morays may not accept all cleaner wrasses!  Anglers, Frogfish, and the like may be dangerous companions.

  • Temperament: Peaceful
  • Compatible with:
    • Same species - conspecifics: Yes
    • Peaceful fish (gobies, dartfish, assessors, fairy wrasses): Safe
    • Semi-Aggressive (anthias, clownfish, dwarf angels): Safe
    • Aggressive (dottybacks, 6-line & 8-line wrasse, damselfish): Safe
    • Large Semi-Aggressive (tangs, large angels, large wrasses): Monitor - For the most part, all tank mates will appreciate cleaning and so will not attempt to eat cleaner wrasses. Notable exceptions include large morays, anglers, and frogfish.
    • Large Aggressive, Predatory (lionfish, groupers, soapfish): Monitor
    • Slow Swimmers & Eaters (seahorses, pipefish, mandarins): Safe
    • Anemones: Safe

Sex: Sexual differences

   Unknown, the gender of the Bluestreak Cleaner Wrasse cannot be distinguished visually.

Breeding / Reproduction

   Pairs regularly spawn in aquariums, but success is rare. The courtship ritual is especially interesting. The eggs, which are about the same size as the pygmy angelfish (Centropyge) eggs, are released into the water column. This happens once per day during the twilight hours.


   The Common Cleaner Wrasse is often available both in pet stores and on the internet. However due to the extremely low success rate in keeping them alive, they are not recommend for the home marine aquarium. Be sure to carefully consider your impact on this species and on the ornamental fish industry as a whole before purchasing these fish.

I've had 4 cleaner wrasses for over a year. One is much larger than the other three. She has been getting fat lately and I assumed it was because she was well-fed. Last night I thought I was losing her because she was swimming very erratically when she released a bunch of eggs into the water!!! She was not dying after all!

I currently have Blue Cleaner Wrasse in one of my reef tanks and so far is doing well. When I put him in my Clown Surgeon needed a clean up. He got straight to work servicing him and my Purple Tang, he now keeps an eye on the Blenny and Gobbie that live here. He always went crazy for frozen shrimp but has now started to eat anything I put in be it frozen or dried foods. He eats all flakes loves Chlorella and Micro Green Pellets swallows the Blood Worms in one along with the Heart and Prawn mix by Marine Fuel. I am out in NZ and we have a great supplier here called Eastern Marine who Sources us a lot of Australian live stock. As a lot of us know Australians do a really good job of getting these things from the see and keeping them top notch. Matt at Easrern Marine is also very passionate about what he’s doing and keeps them this way for us to purchase. I believe this is a major key to keeping some of these things alive. I also think there are fish out their that we give you more problems that can take more than them selves out of your marine aquarium when it happens, such as the Powder Blue, Archilies tangs and other members of its family or the Moorish Idol that doesn’t want to eat or even a Copper Band Butterfly, so why not the fuss about these guys remaining in the see as they are going to give problems that will exceed the Blue Cleaner Wrasse. “CJ.

Hi, I have had 2 cleaner Wrasse in my 900 litre fish only tank for about 6 months. Before I bought them I studied their eating habits in the shop (already being aware of their apparent difficulty) I’m not that seasoned in keeping marines but have kept tropicals including discus for about 10 yrs. My thoughts were if they’re gonna be kept in an aquarium I’d rather it be my 8ft tank thank somebody else’s 3 foot. They eat anything that goes in the tank, in fact they eat more prepared or frozen foods than they do mucus and the like from other fish. I think the advancement in tank husbandry allows hobbyists to better take care of their animals than in the past. With the Biologists who frequent these forums who say these fish should be left in the ocean I whole heartedly agree- I believe they should all be left in their natural habitat but unfortunately that is never going to happen so I would just prefer the people who buy these beautiful creatures to ensure that they research their fish properly and do everything in their power to provide them with the best environment that they are able.
