How to keep red arowana? These care tips you need to master

Arowana is an ornamental fish that many people like to keep, and among arowanas, the red arowana is considered the most popular. So red arowana feeding has always been a topic of discussion among fish keepers. How exactly should red arowana be kept so it gets better and better? We need to learn the methods of keeping red arowana step by step. I believe the following methods will be helpful to you.

How to keep red arowana

1. It is a beautiful large freshwater fish. Arowana normally has a greenish-silver sheen on its body, and because the scales are very large, when illuminated by light they can reflect a pink glow, while at the same time the fins have a beautiful pink or orange-red color. These are the incomparable looks it has among tropical fish.

2. It is a carnivorous fish. When keeping arowana, animal-based bait is generally used, and among these, feeding live small fish is the best. Because animal offal can easily harm the arowana's digestive system, it cannot be used for feeding. You can choose artificial compound feed for prawns, and pay attention to keeping the arowana's nutrition balanced.

3. The most obvious among these is that the arowana has a low-water-volume zipper-like mouth structure, as well as huge scales and fins unsuitable for fast swimming; these are all important features of a “prehistoric fish.”

Precautions for keeping red arowana

1. To ensure the health of the fish in your tank, good water quality is very important. If you do not change the water continuously, harmful substances in the water multiply, leading to continuous outbreaks of fish disease, and even if you use medication for prevention and treatment it will all be wasted effort. When feeding the fish, you just casually toss in some fish food without caring whether it is eaten. This causes a large amount of leftover bait to seep into the bottom of the pool and pollute the water quality.

2. So you should often take the time to change the water for the fish; changing out 1/3 is enough. Wait until the old water and new water are at the same temperature before putting the golden arowana in, and feed in an appropriate amount, just enough for the fish to eat all the bait; do not overfeed, as this is not good for keeping the water clean. If conditions permit, an oxygenator can be installed.

3. The number of fish must absolutely not be too many; keeping 1 arowana in a 1.5m long fish tank is best. Pay attention to increasing the dissolved oxygen in the water, and do not rely entirely on aquatic plants for the dissolved oxygen issue. Because the amount of oxygen produced by aquatic plants is very small, it is not enough to guarantee the normal growth of the arowana.

Disease prevention and treatment for red arowana

1. Cloudy eyes: a white turbidity appears on the surface of the eyeball, indicating deterioration of water quality. You should replace 1/3 of the water in the aquarium, raise the water temperature to 30 degrees Celsius, and add antibiotics; after a few days it should improve. In another situation, whitening occurs at or near the center of the eyeball, and even white cotton-like matter grows; this is mostly caused by nutritional imbalance or bacterial infection.

2. Parasite disease: mostly mainly fish fleas or anchor worms. Fish fleas are a flat, disc-shaped crustacean, about one millimeter in diameter, that attach to the fish's skin and suck the fish's blood. Anchor worms are long parasitic worms, usually buried in the fish's muscles, causing ulcers, redness, swelling and congestion at the attachment site, making the arowana restless, rubbing against the tank, and losing appetite. The treatment method is the same as above.

3. Dropsy-like scale standing: the symptom is scales standing up, looking like a pine cone, also called pine cone disease. The cause is deterioration of water quality and bacterial infection. Treatment method: a saltwater bath combined with antibacterial medication can be used, strengthen aeration in the water, and change 1/3 of the water every day.

Best water temperature for red arowana

1. For red arowana, the best water temperature for adult red arowana should be controlled between 28—29 degrees, because if the usual water temperature is too high, once the red arowana becomes ill there is no room to raise the temperature. For juvenile red arowana, the temperature should be appropriately higher, preferably between 30—32 degrees.

2. But red arowana have very strong individual differences. Some arowanas, under lower temperatures, grow more slowly and have more brilliant colors; once the temperature rises, their appetite increases greatly and they grow rapidly, but their color is dreadful to look at. Meanwhile, some red arowanas, under lower temperatures, have poor color and body shape, but once the temperature rises, both body shape and coloration will show outstanding performance.

Keeping red arowana is a kind of leisure and entertainment, and even more so a kind of knowledge. I believe that after reading this article, you already know how to keep red arowana. Understanding how to keep red arowana can help you avoid many mistakes. Remember, when feeding red arowana you must feed small meals more often, and pay attention to the water temperature.
