11Behavior Of Angelfish

Most angelfish are less aggressive than other species of Cichlid. If you notice angelfish having locking lips, they are fighting with others because they try to fight and defend their positions. Angelfish are sometimes territorial from other fishes. They form their school, but they do not cooperate with other schools of fish in their habitat. Angelfishes are caring for their young, they are willing to defend their eggs and take care of the newly hatched larvae.

Feeding Angelfish

Angelfish eat frozen bloodworms, brine shrimp, and meaty fish food because they are primarily omnivores in the wild. They also eat insects, crustaceans, and larvae in the water. Angelfish requires high protein and fiber in their diets. Angelfish in aquariums should also get the same or the majority of nutrition, like in the wild. Tubifex worm is a vital food source of angelfish in the tank or aquarium. These worms provide high protein content that they also get from the wild. There are also pellet foods for angelfish that are high in protein content. Angelfish must be fed at least twice a day, while with mated pairs of angelfish should be fed up to 4 times a day. Angelfish do not usually eat algae or plants. Still, you may feed them with plan foods that will provide them additional fiber in their diet. For less expensive foods, you can feed them with vegetables like spinach and zucchini.

Habitat And Tank Selection

Since Angelfish is a native species from the Amazon River, they are used to live in slow-moving streams, floodplains, and swamps along the Amazon River. The water they live in is often acidic and with little to no salinity. Angelfish live in a swampy condition, with lots of vegetation and excellent sandy substrate.

For home tank or aquarium setups, angelfish should be placed in water with 75 and 82°F and with a 6.8-7 pH level. If you want to have substrates in their aquariums, put fine sand or mud to prevent cuts to their fins and scales. The water flow in the aquarium must have a low amount of flow because they are used to slow-moving streams. The tank or aquarium will need light exposure up to 8 to 12 hours a day. When you are planning to place vegetation in the aquariums, create a small swamp that is safe and will not affect the motions of angelfish. Avoid using large-sized vegetations like pondweed because it can block the light, and it will overcrowd the habitat of the fish.

For the size of the aquarium, you need to have a minimum of 20-25 gallons for two freshwater angelfish. And if you have a small school of freshwater angelfish, you will need at least 85 gallons.

For the angelfish’s mates, choosing a compatible mate for angelfish in an aquarium is quite difficult. It is because they used to live with freshwater Catfish, Silver Arwana, Aramapiama, and other Characins in the Amazon River. You can select Bolivian Ram or Dwarf Cichlid to be the mates of angelfish. But some of the angelfishes are bully to their mates because they tend to defend their territories.

Change In Water

Angelfish are quite sensitive in poor water quality. Freshwater angelfish reacts to massive water changes. To properly maintain your angelfish behavior in the tank, you can change 50% of the water daily. These frequent water changes will give the angelfish a suitable habitat and will let the fish grow rapidly. With frequent water changes, you can prevent the growth of illness and diseases that can affect the health of angelfish. It also keeps the excellent condition of the environment in the aquarium that establishes a better habitat for fishes.

Breeding And Reproduction Of Angelfish

When angelfish lay eggs, it is placed on vertical surfaces like woods or leaves and even on the glass of an aquarium. Angelfish can breed in water with 75-80°F with a 7.5 pH level. Once the parent angelfish place the eggs, it is ideal for removing the parent angelfish, preventing them from eating the eggs. To condition, the angelfish, feed them with high-quality foods that will increase their successful hatches.
