Requires a weekly change of 50% of the water volume.For one adult, the capacity must be at least 300 liters.Keeping moray eels in aquariums is very difficult. For a comfortable stay of fish in the aquarium, you should adhere to the following rules: In mangrove swamps, in the estuaries of rivers with variable salinity due to the effects of ebb and flow, you can find freshwater moray eels, which can stay in fresh water for a long time. Its habitat is considered to be the coastal regions of the Pacific Ocean – from Australia to India. For most of their life, the fish are in shelters, trapping the prey that has passed. They love shallow waters, coral reefs, gorges and other shelters. They rarely sink to a depth of more than 40 m. Most moray eels prefer warm salty waters. They are common in the Red and Mediterranean Seas, in certain areas of the Indian, Pacific, Atlantic oceans. There were cases of manifestation of aggression against a person. The predatory fish bites into the body and does not open its jaws until it separates a piece of flesh. After swallowing, it attacks again. The fish can lurk and wait. Nasal tubes protrude from the nostrils of the moray eel, contributing to the rapid detection of prey. Then there is an instant throw at the target, using the outer and inner jaws.įish live for a long time, some individuals – up to 30 years. With age, they become more aggressive and can go hunting even during the day. Old individuals are capable of attacking their young relatives. The predator finds prey with the help of the lateral line and a well-developed sense of smell, while vision does not play an important role. A fish is dangerous to humans only when a person, through negligence, disturbed a predator. Moray eels are nocturnal predators. With the sunset, they get out from behind shelters to actively hunt, but they do not chase after prey, but eat all the living creatures that meet on their way. Their favorite delicacy is octopuses, for which they can arrange a chase. Moray eels are solitary animals, although they live in shelters on the same territory, next to each other. The lifestyle and habitat of the fish is extremely interesting. Freshwater Moray eeels lifestyle and characteristics These fish in nature can reach gigantic sizes – up to 370 cm in length and weigh more than 40 kg. Their average length is 60 cm, and the aquarium individuals are half as large. Green Moray Eels leopard moray eel Greyface moray eel Types of moray eels for aquarium The camouflage color of moray eels is different, depending on the type and conditions of existence. It can be brown or gray in color, and have a small spot. The belly of all fish of this species is light in color, monochromatic.The pelvic and pectoral fins are absent. Predators move in the water column, like snakes, actively bending their bodies. But they cannot develop high speed in water.You can observe the tail fin of the vertical type, which provides the fish with mobility and maneuverability during movement.The flattened body is covered with hard skin, without scales, which is often smeared with a thick layer of mucus. The secret helps fish to penetrate into narrow shelters without traumatizing the body on sharp stones.Predators have a large head on a snake-like elongated body. On the head there are rounded gill openings, a large jaw with sharp hooked teeth and eyes with an evil expression.įor more oxygenation, the mouth of the fish is almost always open, allowing large volumes of water to pass through. Some species of moray eels have internal teeth in the pharynx, which, when attacked, move forward and, seizing prey, drag it into the esophagus. So, tetrapods evolved into moray eels. But not all scientists agree with this hypothesis. Scientists suggest that animals descended from tetrapods, the ancestors of alligators, crocodiles, and other four-legged amphibians who preferred to live near small bodies of water, in shallow waters with many reefs, rocks, gorges. There are types of moray eels in which the body is covered with poisonous mucus and such moray eels can burn a person by touching.ĭue to the abundance of food in the aquatic environment, they did not need to get out on land. As a result of the aquatic and terrestrial way of life, the hind legs of the ancestors of the animal were transformed first into fins, and then, due to lack of need, disappeared altogether. ![]()
