Blue tang fish are a popular aquarium fish that can be found in many homes across the world. They are known for their beautiful blue color and vibrant personality. The name “blue tang” comes from the fact that the fish has a bright blue dorsal fin.

Blue tangs can be found in the wild around Indonesia, the Philippines, and Papua New Guinea. They live in schools of up to 100 individuals and feed on algae and other small crustaceans including amphipods (tiny crustaceans).

In captivity, blue tangs eat algae wafers or flakes as well as frozen foods such as krill and plankton. They also enjoy live brine shrimp and other meaty food items such as silversides and squid rings. Their diet should be supplemented with calcium carbonate blocks or flakes so they can develop properly and keep their brilliant coloration.

Blue tang fish are beautiful, and they’re also one of the most popular aquarium fish. It’s no surprise; they have an array of colors that can range from blue to green to yellow. They’re also very hardy and easy to care for, which makes them ideal for beginning aquarists.

If you’re looking to keep blue tang fish in your tank, it’s important to know what they eat. You don’t want to feed them something that will make them sick or even kill them.

Here are some examples of the kinds of foods that blue tangs should be eating:

Live foods such as brine shrimp and mysis shrimp (which can be purchased online)

Algae wafers

Frozen brine shrimp/artemia (which can be found at many pet stores)

Frozen krill/plankton (which can also be found at many pet stores).

When you keep blue tang fish in your aquarium, you’re likely wondering what they eat. Here are a few tips on feeding your fish. You’ll learn more about what blue tangs need to survive, their habitat, and how to prevent the dreaded “hole in the head” syndrome. Also, learn more about how to care for blue tangs. But first, let’s talk about what blue tang eggs look like. These tiny eggs are just 0.8 mm in diameter, containing a single droplet of oil. Upon fertilization, the eggs hatch in 24 hours, revealing tiny translucent larvae. Young blue tangs start off with a bright yellow color with blue spots near their eyes.

Feeding blue tangs

Blue Tangs are large tank fish, reaching a maximum size of 10-12 inches as adults. They need at least 150-180 gallons of water with good current to thrive. Also known as surgeonfish, Blue Tangs have a retractable spine on both sides of their tails. When relaxed, the spine lies flat. However, it will push outwards if the fish is aggressive. The right amount of food and water temperature will keep blue tangs healthy and happy for many years.

Blue Tangs are not suitable for beginners, as they are delicate and sensitive to fluctuations in water quality. Their sensitive temperaments and unique dietary requirements require careful attention. If not treated properly, they can develop harmful ammonia and nitrite levels. For these reasons, it is recommended to use a live rock to provide ample grazing opportunities for your fish. It is also advisable to quarantine the new additions to the tank for at least two weeks. You should monitor their condition for signs of saltwater disease, and gradually acclimate the tangs to their new home.

Blue tangs are omnivorous saltwater fish that require a combination of green and meaty foods to thrive. For green foods, you can use veggie clips. However, you can also buy seaweed sheets from a grocery store. Unlike other seaweed products, nori can be found in grocery stores. In addition to supplemental green foods, you should also provide plenty of live rock for your tangs.


Listed as Least Concern by the International Union for Conservation of Nature, the blue tang is a small fish native to reefs in the Indo-Pacific region. Their habitat consists of tropical and subtropical coastal waters. IUCN notes that blue tangs are essential for the health of coral reefs because without them, the algae population would suffocate and ultimately wipe out the coral. The IUCN lists the blue tang as a least concern fish, but in fact the fish trade has impacted the species’ numbers.

The blue tang is a small fish with a distinctive tail and body color. Once acclimated to the tank, it will start establishing its territory and may become aggressive towards other blue tangs. While similar tangs can be kept together, they should be separated once they mature. If you plan to keep more than one, choose different species or even a different genus. This way, you can ensure that your tangs are not in conflict with each other.

Female blue tangs are larger than males and reach sexual maturity at nine to twelve months of age. During the breeding season, they may breed in pairs. The fertilized eggs take about 25 to 28 hours to hatch and the resulting juvenile blue tang takes about 37 days to develop. The blue tang is an excellent choice for aquarists, because it is a great addition to a reef aquarium. When the blue tang reproduces, its population is managed by removing harmful algae that can lead to overgrowth of coral.


If you are considering keeping a Blue Tang in your aquarium, you need to learn about its diet first. These fish are surgeonfish and are renowned for their spines that can stand up against predators. They live in the clear waters of coral reefs and are thought to be around one-quarter of a million strong. However, despite their beauty, they are also quite dangerous. If you do happen to catch one, you need to know how to deal with its venomous spines.

Most blue tang owners prefer to give their fish seaweed, but some other seaweed varieties may also be provided. A variety of seaweed will also work well, such as nori. In addition to these, you can provide rocks or vegetables as grazing platforms for your blue tang. You should also provide some type of nutrient-dense supplement, as a lack of these will cause its colors to fade.

The diet of Blue Tangs is dominated by algal species. As a result, their primary food source is algae. Nevertheless, the presence of other marine animals will inevitably cause high competition in algal grazing areas. Also, these fish often occupy single reef environments, thereby exerting extreme pressure on their population. So, while their diet isn’t complex, it is crucial to keep their habitat healthy and well-protected.

Hole in the head syndrome

The cause of Hole in the Head Syndrome (HITH) in blue tang fish is still unknown. Most often, this condition is caused by an infection with Hexamita, a parasite that lives in water and infects fish. This parasite attacks the brain and spinal cord and causes inflammation. This inflammation eventually leads to a hole in the head. In many cases, the condition is treatable, but it is not always possible to prevent it.

The pits on the fish’s head are usually slightly depressed and are a dark grey, white, or brown color. More severe infections may erode large patches of the fish’s sides and face. However, in most cases, these erosions start out as a single or multiple pinpoint-sized defect. However, it is important to note that the disease is not confined to blue tangs. Angelfish and surgeonfish are also susceptible to hole in the head syndrome.

Some tangs are sensitive to copper, which can lead to this condition. Activated carbon is another potential cause of Hole in the Head Syndrome. The best way to avoid this degenerative disease is to provide a stress-free environment and a quarantine tank for the fish. Ensure that the water quality is high enough and the tang has access to a refugium. A refugium will help remove excess nitrogen, phosphorus, and nitrates, and provide a peaceful environment for the fish.

Breeding in captivity

In 2012, biologist Kevin Barden and a group of UF researchers took a leap and began breeding blue tangs in captivity. They put in long hours, holidays, and weekends to develop breeding techniques and create an environment mimicking the Pacific Ocean. Their larvae passed the six-day bottleneck and grew to full size in just a few weeks. Despite these challenges, their efforts paid off.

While blue tangs can live with other marine species, it is not recommended. Their behavior can be temperamental and stressful if they are kept with too many other fish in the tank. While they are peaceful and do not bite, they do not do well when kept with other aggressive fish. These fish need plenty of space and a varied diet to thrive. You can provide them with marine seaweed as a supplement to their diet to prevent their colors from fading.

The blue tang needs oxygenated water and a constant movement on the water surface. Power heads and wave makers can help achieve this. Ensure that your aquarium has a full nitrogen cycle before adding blue tangs. Blue tangs are relatively hardy, but they require an established setup. In addition, they need to be housed in a tank of at least 30 gallons. The water must be completely clear to avoid disease.

Threats to the species

Among the most common threats to Blue Tangs is ich, which is caused by parasitic organisms and can cause severe infections. Fortunately, this parasitic disease can be treated. The first step is to identify the symptom. Ich-affected fish have white spots on their bodies and will try to scratch at rocks and decor. If you see this behavior in your Blue Tang, it is likely that he or she has ich. Here are some treatments you can use.

To ward off the dangers that a Blue tang may face, it is important to be aware of its appearance and habits. The blue tang’s body is pancake-shaped, with small scales on its sides and a pointed snout. The blue tang’s mouth is small and its eye is located high on its head. The blue tang’s spine is venomous, and the fish whips its body when it senses a predator is nearby. It uses these venomous spines to protect itself from predators and to warn other fish in the area that it is in danger.

The blue tang’s habitat is tropical and subtropical coastal waters, and there is no official international population data. Although they are not threatened or endangered, the species is often caught for the aquarium trade. It is also sometimes used for bait. Its spine on both sides of its caudal pediculum can cause painful wounds in the event it gets bitten. In addition to cyanide squirt bottles, the blue tang’s habitat is being affected by ocean acidification and coral lightening.
