Longnose Hawkfish are native to tropical waters, and are commonly found in saltwater aquariums. They are a beautiful fish, and are known for having long fins that resemble wings. They are very easy to care for, and will accept a wide range of water conditions. They are not aggressive towards other fish, and will usually avoid fighting unless provoked.
The Longnose Hawkfish is a great fish for your family’s aquarium. If your aquarium has a lot of rocks and caves, you will definitely want to add this fish. They will use the caves to hide during the day and come out at night to feed. They can grow up to 6 inches long, but most will be smaller.
The Longnose Hawkfish is best kept in an aquarium with a sandy bottom so they can stay hidden. As you can guess based on the name, the Longnose Hawkfish has a prominent long snout, much like a hawk. They will perch themselves on top of the rocks hoping to be camouflaged. They won’t be completely invisible but it will be harder to see them.
The Longnose Hawkfish, also known as the Hawkfish, is probably the most unique fish available in pet stores today. They have vertical mouths, large eyes, and a spiky body covered in scales. Despite all these intimidating features, the Longnose Hawkfish is not overly aggressive towards other fish. They are a hardy fish when it comes to surviving in an aquarium environment.
These fish can be black, brown, or red, or any combination of the three. They have two long dorsal fins that extend from the top of their head to the bottom of their tail fin.

Temperament of Longnose Hawkfish
Longnose Hawkfish are semi aggressive and also very curious. They enjoy perching on branches or rocks in their aquarium, jumping whenever it notices some activity, but will hop right back to their perch after exploring.

They are very fast swimmers and have also been known to jump out of open tanks. Because of their tendency to jump you’ll want to keep your aquarium covered to keep your fish from jumping out.
Best Tank mates for Longnose Hawkfish
Most aquarists prefer keeping only one Longnose Hawkfish in a tank to avoid dealing with their aggressive behavior. Placing more than one Hawkfish in a tank could lead to fatal battles unless you have a very large tank that can hold at least 100 gallons. Here are some good tank mates for your fish as long as you add the Longnose Hawkfish last.
- Damselfish
- Average sized Wrasses
- Gobies
- Blennies
- Dwarf Angelfish
- Dottyback Fish
- Large sized worms and crustaceans
You should never place your Longnose Hawkfish with marine creatures that sting because your fish could become a target for them. Some of the creatures to avoid include the sea anemones and Catalaphyllia corals.
Tank Conditions for Longnose Hawkfish
They should be kept in a tank that’s at least 30 gallons to give it plenty of space to swim. The tank should also have lots of coral and rocks for them to perch on. Longnose Hawkfish don’t have swim bladders. If they aren’t swimming, they tend to sink to the bottom of the tank. That’s the reason why they perch on objects, to prevent sinking.
The temperatures for your Longnose Hawkfish should be kept between 72 and 78 degrees Fahrenheit. These are the exact temperatures available in their natural habitat. Having a thermometer in the aquarium can help you monitor any slight changes in the temperatures of the water. In larger tanks it’s best to have a thermometer on each end of the tank to make sure the heat is consistent throughout.
The salinity in the aquarium should be between 1.020-1.025. The pH of the water should also be kept between 8 and 8.4. Water testing kits are necessary to make sure that the water conditions remain at optimal levels.
They don’t need bright lighting because in the wild the fish is often found very deep in the water where there is much less natural light. It’s best to mimic their natural habitat as much as possible, but lighting can still be used. Using an LED strip the lighting can be set up so that it’s dimmed, or even tinted a dark blue to reduce the intensity of the lighting.

Marine Velvet Disease, also known as Velvet Disease or Coral Fish Disease, is a parasitic infection that affects saltwater fish. It’s caused by the dinoflagellate called Amyloodinium ocellatum, which attaches itself to a fish’s skin, gills, and fins.
The first signs of Marine Velvet Disease are usually a yellowish-gold dusting or velvet-like film on the fish’s skin. As the infection progresses, affected fish can become lethargic, lose their appetite, and display rapid breathing or gasping for air. In severe cases, Marine Velvet Disease can be fatal.
Symptoms of Marine Velvet Disease
Symptoms of Marine Velvet Disease include:
- Yellowish-gold dusting or velvet-like film on the fish’s skin
- Lethargy

In severe cases, affected fish can also develop open sores and have abnormal swimming behavior.
Feeding Longnose Hawkfish
Longnose Hawkfish are mainly carnivorous but in the aquarium, they can eat a combination of plants, flakes and meat. Brine shrimp, small fish, and other crustaceans make a good meal for your Longnose Hawkfish. Live foods are preferred over frozen ones because it gives your pet food close to what they ate in their natural habitat.
It’s also advisable to dip fish flakes, frozen, or live foods in vitamin or garlic powder to boost their immunity. Longnose Hawkfish should be fed twice a day and make sure everything gets eaten to avoid contaminating the water. If you notice that some food doesn’t get eaten, feed the fish slowly allowing them to finish one piece of food before you can drop another one.

Can I Breed Longnose Hawkfish in My Aquarium?
If you have a male and a female in a single tank, you’ll notice that during mating they tend to swim together near the surface of the tank. The practice is usually called the courtship dance. If you’re lucky enough to be there when it happens, the eggs and the sperm look like cloudy spots in your tank.
The eggs are very fragile and may be eaten by other fish or die before hatching. Very few fries make it to adulthood.
