How to Treat Popeye in Fish

A fish suffering a popeye disease can be dangerous because it can lead to the fish losing their eyesight or even losing the eye itself. But how to treat popeye in fish? Please check different tips and tricks to treat it and prevent the disease from infecting the aquarium.

Treating a Popeye Disease Cause By an Injury

Treating a popeye disease in a fish will depend on what is the cause of the disease. If an injury causes it, the best treatment you can provide is to let it heal on its own. This treatment is effective as long as the eye will not develop any secondary infection.

You can also provide additional care, such as using an aquarium salt to help in relieving the swelling. This care will enhance the chances of the eye being treated quickly as the absence of the swelling can help make the eye recover fast.

Removal of Dangerous Tank Decorations

One way for the fish to have an injured eye that can cause popeye is those sharp and pointed decorations. To prevent further injury, you can remove all those rough and pointed rocks, pointed and shard plants, and other aquarium decoratives with sharp and pointed edges.

Regular Water Changes and Monitoring of its Chemistry

During the recovery time of the fish, you will need to do water changes regularly while also constantly monitoring the water chemistry. It should be noted that the common cause of popeye is the poor water condition.

Hence, consistently doing water testing is needed to check if there is any problem with the water chemistry. Among those that need to be tested are the pH level and ammonia or nitrite concentration.

Removing the Fish From Aquarium

If you think that the fish already suffers from bacterial infection, you will need to separate the infected fish into a separate tank. You can call this fish tank a quarantine tank which will help to prevent the fish from infecting the other.

Then, you can use an antibiotic recommended by your veterinarian or pet supplier to address the bacteria in your fish. If multiple fish are infected with bacteria, you can consider treating the whole main aquarium to kill all the bacteria.
