The body appears to be divided in half by the comb on the back. The tail and the anal and dorsal fins are similar. The ventral fins are either nonexistent or very poorly developed.

The color is mostly light brown, though it frequently varies depending on the person’s living situation. It can grow to enormous sizes with proper care. fish with a different color on their abdomen, which is typically brighter than their main color.

It is imperative to cover the aquarium because macronatus can squeeze through any opening. In the aquarium, a filter with a moderate to strong water flow is advised. Since the fish dislike direct sunlight, you must provide shade for them in the aquarium by adding plants or using moderate lighting that will be turned off at night. It is advised to add 3–4 tablespoons of sea salt per 100 liters of water to help the fish feel at home, but remember that salt can also harm other nearby fish. The aquarium should have an effective aeration and filtration system because macrognathhus prefer clean, oxygenated water.

Fundamental guidelines for maintaining:

1. The aquarium should be covered with a lid, because the fish can crawl out even into the smallest cracks.
2. From time to time, the water needs to be salted.
3. The tank should have a good filtration and aeration system.
4. Once a week, 25% of the water in the aquarium should be changed; once every two weeks, the water should be completely changed.
5. The temperature level should be maintained all year round.

The macrognathus physiology necessitates the elimination of mucus secretions, which occur frequently. Fish routinely burrow into the earth or rub against big stones to get rid of excess mucus, which can cause diseases. It is dangerous and inconvenient to burrow oneself among sharp stones, so be sure to check the gravel you are laying out for any particles that could harm the fish. There should be at least 10–12 cm of soil underneath. Large-washed sand is an excellent option as well.

You can decorate with driftwood, rounded stones, and ornaments without sharp edges. However, it is advised to only occasionally lay them out to give the fish a place to swim. In order to prevent fish from pulling plants out of the soil while they are digging, plants should have developed root systems. In the event that none exist, the plants ought to be planted in the aquarium alongside specialized pots to increase their stability. It is beneficial to leave voids between plants so that fish can burrow into them.

How individuals reproduce

When spawning season starts, the males start chasing the females when they hide. Because Macrognathus reproduces poorly in captivity, you will need to administer injections of special hormones into the back muscle. Without the need for injections, spontaneous spawning can occasionally happen. In 11–14 hours, the fish are prepared for mating. The breeding pair is moved into a tank and fed a special high-protein diet in large quantities. It is also possible to transfer two males and a female.

The spawning tank needs to be at least one meter long and twenty liters at the very least. Installing an aeration system and a high-quality filter in the aquarium is recommended. In order to bring the macrognathus closer to their natural habitat, where spawning takes place during the rainy season, the water hardness should be lower than in the main aquarium.

The spawning tank’s water should be 26 °C, a plastic net should be placed on the bottom, and small plants and moss should be added. A few hours pass during spawning. It is best to avoid disturbing the fish during this time.

When the fish become lethargic and start digging in the ground, it means that spawning is over and the young need to be moved into a regular aquarium. Approximately a thousand eggs are released during spawning, and these either attach to the tank walls and plants or sink to the bottom of the aquarium. In 3–4 days, fry appear. They feed on the yolk sac for a few days before switching to independent feeding. They should eat mostly brine shrimp and worms, along with some crushed dry fish food. The water temperature should not be higher than 26 to 28 °C in order to preserve their health.

Regular water changes and the use of fungus-destroying preparations are required to prevent diseases in young fish. The growth of the young fish must be observed, and they must be divided and arranged according to size.

Feeding

Being carnivorous fish, macrognathhus consume small invertebrates, crustaceans, worms, and insect larvae as food. They are able to pursue small fish. Most commonly, frozen natural food (bloodworms, brine shrimp) and occasionally finely chopped fish, squid, and shrimp pieces are fed to aquarium inhabitants.

Dry food and flakes should only be used occasionally as a vitamin supplement.

Feed the fish three to four times a week while the lights are off or in the dark. To prevent the aquarium from becoming dirty, remove any food that is not consumed in three to five minutes. Monitoring the feeding process is necessary to ensure that every person receives food. Certain fish can be eaten with your hands.

Macrognathus has the ability to alter its eating habits or to completely reject food.

Supplements with dry vitamins are also advised.

Compatibility with other species

Although Macrognathus is not aggressive, it may begin to hunt small fish in the aquarium. Purchasing young fish from small schools is preferable since it will help them adapt. Adults should be kept apart for the best. It’s not a good idea to keep a large number of them in one aquarium because males will frequently fight over territory or during spawning.
