About What Do Shark Catfish Eat: People eat many different kinds of fish in the ocean. They are called sharks, and everybody loves them because they taste good.

Catfish have also been known to eat turtle eggs when they can find them while searching for food on the bottom of a lake or pond.

What Do Shark Catfish Eat?

Shark Catfish are very beautiful looking fish. They can grow up to about six feet long and weigh almost a hundred pounds.

They are catfish and not sharks, and nobody can tell the difference. Catfish usually live in freshwater lakes.

Because they eat plants, algae, and tiny fish that live in the water, their skin is bright green, although it turns brown when the fish is dead or when it ages.

Most catfish are small because they eat tiny creatures that live in small streams or marshes.

Shark Catfish Facts

Shark catfish grow fast. By the time they have grown to twenty inches long, they are as big as many of the larger fish we eat.

They are very strong, and they can swim much faster than other fish. To keep them alive, some people keep them in a small pond or lake that has only a few feet of depth.

This way, the catfish won’t be too hard to catch and eat. Catfish and shark catfish can stay alive in freshwater or saltwater.

They breathe air out of the water, but they live in the ocean. When it is time to lay eggs, these fish float on top of the water to release them.

Sometimes, their eggs float away and end up lying on land. One very interesting thing about shark catfish is that they called a school together to swim.

Sharks And The Food They Eat

There are many different kinds of sharks in the sea that eat different things to stay alive. Some eat lots of other fish, and some eat only small things like plankton and algae.

Some sharks are very large and have huge teeth, but small sharks have tiny teeth. The smallest shark found is a little less than one foot long.

When the biggest shark was found, it was about sixty feet long and weighed about three hundred and fifty pounds. That was the largest shark ever to be seen.


Shark Catfish are also very different than their shark cousins. They are more like fish than like a shark.

They have scales, and some even have a heavy bottom jaw. An interesting feature present in almost all shark catfish is the back fin which resembles a fin on a dolphin’s body.

Another interesting thing about catfish is that the male catfish has larger fins than the female catfish to make it look like smaller fins.

  • Habitat: Distribution / Background
  • Scientific Name: Arius felis
  • Arius felis = Arabian Bitter Catfish; Bronze Whiptail Catfish; Tigre Whiptail Catfish; Leopard Whiptail Catfish
  • The Arius felis is the Arabian bitter catfish, bronze whiptail catfish, tiger whiptail catfish, and leopard whiptail catfish.
  • Other similar species belong to the same genus. This species is known to grow up to 6 inches (15.2 cm).

It is found in the Mascarene Islands of Mauritius and Reunion. This species is highly threatened and near extinction because of predation by introduced fishes and habitat destruction due to agriculture and fishing.

In 1989, the only place with this species was a small pond in Mauritius; it has not been seen since 1993.


Shark Catfish have a silver, long and pouty face. Shark Catfish have vertical fins that are black with a white border.

Black spots sit on the lower part of the body and the tail fin. The dorsal fin is also black with a white border.

They have wavy stripes that start blue then turn white near the belly, which could be an image of a shark. These markings give the shark catfish their name.


The Arius felis finds its food in shallow waters and caves in the mud along river banks and the mangroves.

It is also a carnivore but does not eat other fish. They prey on small snails in the mud and small crabs and insects.

They feed mainly at night when they come out to hunt or to look for food, so they are nocturnal animals.

Shark Catfish Keeping Difficulty

The Arius felis is not very difficult to keep. It needs a cool temperature and some water with a high oxygen level. If it doesn’t have enough food, it will become lethargic and stop feeding.

Foods and Feeding

The Arius felis is a carnivore. They will eat anything they can get their mouth on.

They should be kept with meaty foods like shrimp, squid, fish, and scallop, gut-loaded.

Keep your shark catfish happy by offering live or frozen blood worms, tubifex worms, brine shrimp, mosquito larvae, beef heart, and other types of meaty foods. They should be fed two to five times a day.

The Social Behavior Of Shark Catfish

They are very shy and tend to burrow in the mud under rocks when they feel threatened. They can also move around by walking on their fins, like a walk on all fours.

They are found alone, but there may be more than one in an area with lots of prey and food.

They do not like to be kept in schools; they prefer an alone life. They can be kept with other fish that are not very aggressive.

Aquarium Setup

Shark Catfish need to be in a 75-gallon tank or larger. They are active swimmers and will dart around the tank.

They can sometimes get caught on the glass. The tank needs to have a secure lid and need at least one driftwood branch per square foot of aquarium surface to prevent the shark catfish from getting tangled in the branches of wood which can cause injury or even death.

You should also provide an abundance of hiding places for the shark catfish so that they will feel safe and secure.

Aquarium Care

The Arius felis cannot tolerate any salt in the aquarium. It is recommended to keep the water in the aquarium at a temperature between 72 and 78 degrees Fahrenheit (22- 26 degrees Celsius). The tank should be well lit. Keep an adequate supply of live, meaty foods for this catfish.

Breeding: Does Arius Felis Mate?

This species has been observed spawning in captivity, although there is no known reproduction data from wild populations. Like many other livebearers, it is suspected to be similar to the platy behavior.

Sexual Differences

Males can be identified by their larger fins.

Shark Catfish Breeding/Reproduction

To breed this fish, you need two connected tanks of different sizes. The smaller tank should be around 2 feet long and 6 to 8 inches high.

The bigger tank should be at least 4 feet long and 16 inches high. It would help if you used a sponge to block the opening of the connecting tubing so that egg-laying would not happen.

Then, you need to make an area in one corner where aquarium plants can be kept so that the eggs will not be lost.

When it’s time to breed, you should give the male a female and mix them in the tank. The male shark catfish will try to mate with all females to have eggs.

Fish Diseases

The Arius felis is prone to skin flukes, parasitic infestations (protozoa, worms, etc.), ichthyology infection, and bacterial infections.

The Arius felis can be treated with medicine that the fish keeper adds to the aquarium. Aquarium keepers should monitor the fish to ensure no reaction to the medicine. It is important to treat all fish for them to get well.
