Common causes of Arowana eye loss
Arowana eye loss can generally be divided into The following three parts:
I. Congenital ophthalmia
Some dragon fish are congenital ophthalmia. Certain measures try to help it improve the situation.
2. Eye drop phenomenon caused by factors in the tank
1. Feeding factors
Some owners are feeding In the process of arowana, they are often fed some dead small fish and shrimp, but this kind of food will sink directly to the bottom of the tank after being put into the water, so the arowana needs to swim to the bottom of the tank to find food. However, since the dragon fish generally likes to swim near the water surface, it needs to look down when it goes to the bottom of the tank to find food. Over time, it is easy to cause the dragon fish to lose its eyes.
2. Fish tank height and water level height
If the water level in the fish tank
or tank is too high, the arowanas that frequently move on the upper floor will also look down frequently, Too much frequency will cause the dragon fish to lose its eyes in the long run.
3. There is a reflective bottom plate at the bottom of the tank.
Some owners choose some materials that are easy to reflect light when laying the bottom of the tank. The lights will cause reflections and reflections at the bottom of the dragon tank, and the dragon fish will continue to look down at the reflection and reflection at the bottom of the tank out of curiosity, which will cause the dragon fish to lose eyes in the long run.
4. Top scene setting in the tank
Many owners will set the tank cover above the tank where the arowana is raised, but doing so will easily prevent the arowana from looking up, and it may also cause the arowana to look up. Causes the phenomenon of dragon fish eye drop. Even if the cylinder head is transparent, it may not attract the dragon fish to look up.
Three, Arowana eye drop phenomenon caused by factors outside the tank
1. Light influence
If the location of the aquarium is not good or the lighting near the fish tank is too long, these factors will make the dragon fish feel uncomfortable, and the dragon fish will avoid the light. Then it will keep looking downstream or down, resulting in the phenomenon of eye drop.
2. External influences
Arowana lives in the fish tank for a long time, and the life is relatively monotonous. If there are often small animals or children shorter than the fish tank, it may attract the arowana Looking down, it may also cause the dragon fish to lose its eyes in the long run.
3. Food selection
In order to quickly gain weight and improve the body shape of arowana, some owners feed them high-fat foods for a long time, but doing so can easily lead to Its eyeball fat accumulates rapidly, and because the arowana lives in the tank, it does not need to forage every day, and its range of activities is limited, so the amount of exercise is relatively small, which will also cause the arowana to lose its eyes faster.
The above are some of the reasons why the dragon fish lost their eyes. I hope this sharing can answer your doubts.
