How To Take Care Black Arowana
The Black Arowana (Osteoglossum ferreirai)
The Black Arowana (Osteoglossum ferreirai), also known as the black dragonfish, blue Arowana or monkey fish, is a South American freshwater bony fish which belongs to the subfamily Osteoglossinae of the family Osteoglossidae. They are also recognized by alternate spellings of Arowana, which include Arahuana, and Arawana, this fish is adored by many hobby aquarists.
The Black Arowana is native to tropical South America and is discovered in Brazil, Guyana, and Colombia, where restricted to the Rio Negro basin, including the Branco River. Although they could also be discovered seasonally in other bodies of water. These species occur in both black and white water habitats, including flooded forests.
The Black Arowana is basically a sedentary (non-migratory) species of blackwater habitats. During the dry season, it primarily inhabits backwaters, marginal lagoons, as well as small tributaries, however, it is frequently seen in flooded forests during the high water season.
The Black Arowana are strong powerful swimmers. They could grow up to 90 cm (35 in) in total length, however, there are reports of individuals up to 120 cm (47 in). Like all Osteoglossum, South American Arowana has fairly large scales, a long body, as well as a tapered tail, with the dorsal and anal fins extending all the way to the small caudal fin, with which they are nearly fused and large eyes.
The Juvenile Black Arowana specimens will display yellow markings over a black background color. Once it reaches about 15 cm (0.49 ft), the markings will disappear as well as display an adult coloration of grey with a bluish tint, hence its common name. Unlike the Silver Arowana, the Black Arowana are yellow and red outlining or the dorsal, caudal as well as tail fins. In contrast to the juveniles, adults of both species are very similar, however, can be separated by meristics.
The Black Arowana has beautifully tapered fins with a large and oblique mouth as well as forked barbels on the point of the lower jaw which is used as a sensory organ, able to detect movement on the water’s surface. They might live for many years. The average Arowanas lifespan is 15-20 years, and if well cared for Arowana fish might live longer than 20 years in captivity.
The Black Arowana is a very hardy fish, however, it could have problems such as gill curl, which is typically due to abnormal water quality as well as limited space. Ich or white spot, cloudy eyes, and also cone scales are the other arowanas illness. Proper care should be taken to protect your fish from these unusual situations.
The Black Arowana like all of the Arowana species is not a fish for beginner fish keepers. They require large fish tanks and also tender, loving care to keep them happy, they are a peaceful species though and become fairly tame. Some Asian aquarists occasionally refer to Arowana as dragonfish because of their unique look and also believe they bring good luck.
Diet Of The Black Arowana
The Black Arowana are carnivorous, which means that they feed just on meat and should be fed a high-quality diet of meaty food, such as shrimp. They are surface feeders and also prefer to take food in the upper parts of the water column.
In the wild, these Black Arowana are a hazard to anything above, on, or below the water surface. It is primary diet consists of crustaceans, smaller fish, insects, and other animals that float on the water surface, which its drawbridge-like mouth is solely adapted for feeding on.
In an aquarium environment, feed them different types of worms, which can include earthworms, crab meat, shrimp, beef heart, crustaceans, and also small frogs. Some Black Arowana can be trained to take pelleted food, however, most of will prefer a meaty diet, with the regular addition of feeder fish.
In addition, juvenile Black Arowana will readily consume small fish, tadpoles larva, live brine shrimp, live brown worms, small earthworms and other live foods, but should be trained to accept pellets, sticks, a chunk of frozen foods, chopped and also whole market shrimp, as well as other meaty foods.
The baby Arowanas should be fed possibly 3 times a day, medium sized twice a day, and adults once a day, or even once every other day. Variety is necessary for a well-balanced diet in Arowanas just like for most other fish. These species are prone to Drop Eye in captivity, so proper care should be taken during feeding.
Reproduction Of The Black Arowana
The Black Arowana are mouthbrooders and are readily bred in large ponds, however, rarely in fish tanks. It should be kept in mind that the few people claiming to have had success typically had tanks well in excess of 500 gallons. Breeding is not difficult once you have a large enough tank.
In the wild, the Black Arowana will typically lay their eggs at the beginning of the flood season. Before spawning, they will pairs up as well as build a circular nest in the mud of the floodplains. The female will lay her eggs into the nest before the male takes the eggs in his mouth.
The Black Arowana reach sexual maturity at about 3 years of age. The females will produce 50-250 eggs, which are fairly large in size and are orange/red. After the eggs are fertilized, the Arowana exhibits great parental care with paternal mouthbrooding. Both the fertilized eggs and larvae are brooded within the male’s mouth.
Typically the ponds are approximately 15m by 20m with a mud or silt floor. Over time, the female will lay eggs on the floor of the pond as well as the male will pass overfertilizing them. Following the fertilization, the eggs are collected into the mouth of the male, where they will develop for 6-8 weeks before being released as young fry into the pond. The fry is typically fairly large, measuring around 50-75 mm during hatching.
How to Aquarium Care for Black Arowana?
The Black Arowana require at least a 250-gallon fish tank. Since they could grow up to 90 cm (35 in) long, while Juveniles will be fine in 60-gallon tank. With adult Arowana, larger is always better. They are territorial and might be kept with other Osteoglossum only in a very large fish tank, provided all fish are of similar size.
In addition, If you plan on keeping multiple adult Arowanas together, do so carefully. They typically don’t get along well together. If you are persistent, you should keep at least 6 of them together. The tank should be placed in low traffic areas to keep the Arowana from getting frightened by sudden movements.
The Black Arowana are excellent jumpers and very strong. Like other Arowanas, they need a tight-fitting cover to prevent escape. The tank should have a substrate of small grain gravel or aquarium safe sand and store-bought pieces of driftwood. It should also be sparingly planted, and have lots of open space for them to move around in.
The Black Arowana eating habits produce a lot of waste and you should consequently, pay extra attention to (Ammonia, Nitrite, and Nitrate) in your fish tank. Strong water filtration is required, in addition to weekly water changes, 25% to 33% is recommended, or better yet, 20% twice a week.
You should maintain the pH neutral. Pay specific attention to the temperature as well as pH ranges, since if you have it too warm, it may cause them to age faster and even shorten their life. The water should be soft to moderately hard, well-filtered, and slightly acidic, and maintained at a temperature of 24-29°C (75-85°F), as well as a pH level between 6.5 and 7.5, are recommended.http://www.animaldiscoveryonline.com/black-arowana/http://www.animaldiscoveryonline.com/wp-content/uploads/2018/05/black-arowana-1.jpghttp://www.animaldiscoveryonline.com/wp-content/uploads/2018/05/black-arowana-1-150x150.jpgArowana FishBlack ArowanaUnderwater AnimalsBlack Arowana,Diet Of The Black Arowana,How to Aquarium Care for Black Arowana,Reproduction Of The Black ArowanaThe Black Arowana (Osteoglossum ferreirai) The Black Arowana (Osteoglossum ferreirai), also known as the black dragonfish, blue Arowana or monkey fish, is a South American freshwater bony fish which belongs to the subfamily Osteoglossinae of the family Osteoglossidae.
