The main reasons for the big eyes of parrotfish are as follows:
Water Quality Issues: The big eyes of parrotfish are usually caused by poor water quality. When harmful substances such as ammonia nitrogen and nitrite in the water quality exceed the standard, or when bacteria and parasites breed due to not changing the water for a long time, it will trigger eye infections and inflammations.
Malnutrition: Inappropriate diet may also cause the symptom of big eyes in parrotfish. The lack of key nutrients will affect the resistance, growth and development of parrotfish, thus leading to eye diseases.
Trauma: Parrotfish in the aquarium may suffer from eye trauma due to reasons such as collisions and abrasions, resulting in swollen and protruding eyes.
Preventive and Therapeutic Measures Include:
Improve Water Quality: Immediately change part of the water, keep the water quality clean, and use a water quality purifier. It is recommended to change the water at least once a week, and change a part of the water volume each time.
Medication Treatment: Antibiotic drugs such as oxytetracycline and gentamicin can be used for treatment. Dissolve them in the water of the fish tank according to the proportion in the instruction manual for a medicated bath treatment, or add the drugs to the feed for feeding.
Nutritional Supplement: Select a nutritionally balanced feed to ensure that parrotfish obtain sufficient nutrition. Vitamins that can enhance immunity can be added to the feed.
Regular Inspection: Regularly test the water quality of the fish tank to keep the water quality stable. Feed reasonably and avoid excessive feeding that may cause water quality pollution. Regularly clean the fish tank and the filtration system to reduce the breeding of bacteria.
