What are the influencing factors of acquired eye loss in dragon fish
1. Feeding
If the owner often feeds some high-protein or high-fat foods to the arowana, it is easy to cause the arowana to lose eyes due to the accumulation of fat in the long run. To ensure that the food is nutritionally balanced, avoid feeding them too much high-protein and high-fat food in order to raise arowana quickly, and pay attention to regular and quantitative feeding.
Because most of the food of arowana is submerged food, such as dead small fish and shrimp, etc., in order to avoid the arowana living in the upper waters often eat at the bottom and cause eye drop. Therefore, it is necessary to pay attention to feeding arowana in small quantities and multiple times to prevent too much bait from sinking to the bottom of the tank, causing the arowana to look downstream frequently. Feed a small amount several times, and wait for the dragon fish to finish feeding before putting it in each time.
2. Water level
Excessive water level will cause the dragon fish who are used to living in the upper layer to develop the habit of looking down, so pay attention to the fish tank
should not be too high, and the water level should not be too high , should be 15-20 cm lower than the height of the fish tank. Lowering the water level is also one of the effective ways to treat Arowana eye drops.
3. Light
The uneven light intensity is also one of the culprits that cause the dragon fish to lose its eyes. Arowana’s eyes have “phototaxis” and “photoshyness”. If the light near the fish tank is too strong, it will prompt the arowana to droop its eyes and avoid the light. In the long run, the eyes of the arowana will experience fatigue of the adjustment mechanism, resulting in eye drop.
For the condition of the arowana’s eyes falling due to the lighting factor, it should start by reducing the strong light exposure, reduce the stimulation of the strong light to the arowana, and at the same time pay attention to keep the light in the tank consistent and the outside The light is relatively stable. Usually, when switching the lights in the tank and the lights in the room, pay attention to keeping the switching sequence and switching time of the lights reasonable and regular. In addition, pay attention to placing the lights in the water reasonably to ensure that the light intensity in the fish tank is reasonable and uniform. The design skills of underwater lights are as follows:
① Reasonably set the upper light source and control the water level, so that the light source in the tank is evenly illuminated on the water surface.
② Match the underwater lights and the top lights of the fish tank reasonably to keep the light in the fish tank more consistent.
③ When using the underwater light, place the underwater light at least 5 cm away from the water surface, and place it in front of it to prevent the fixed light from affecting the dragon fish. In addition, the owner can change the position of the lamp regularly to balance the sight of the arowana.
④ When resting at night, you can use a night light to illuminate the room or cover the fish tank, so as not to suddenly turn on the light and startle the dragon fish.
⑤ In addition, try to prevent the surrounding of the fish tank from being affected by other external light such as TV light, so as not to cause the arowana to drop its eyes on one side.
⑥ The bottom sand or tiles can be properly laid on the bottom of the tank to prevent the arowana from falling out due to the reflection of the bottom surface.
4. Surrounding environment
If the dragon fish is nervous because of timidity or incompatibility with the environment, and curls up in a corner for a long time, if this continues for a long time, the dragon fish will also appear to some extent. down view. In addition, if there are often moving objects outside the aquarium, the Arowana will keep moving with the objects, causing the Arowana to look down habitually, which will also cause the Arowana to lose its eyes. Therefore, families with dragon fish should pay attention to avoid small animals or children walking around the fish tank frequently.
