How to Treat a Bubble Eye Goldfish with a Popped Eye Sack!

Bubble Eye Goldfish are very unique and beautiful in their appearance as they are considered a fancy Goldfish with a double tail that splits and makes four beautiful and graceful points. These fish have fluid-filled sacks under the eyes that make a jiggling in the bubbles as the fish swim around in their tank.

They are prone to pop eye in which the sacks are damaged and they take more care to prevent this than other types of Goldfish, so they may not be a great choice for a novice fish owner.

Bubble Eye Goldfish popped sacks can be the result of several different items. The water quality has to be very good for this type of fish and they can easily injure their eyes on objects in the tank.

Other fish can hurt them in the tank also and easily cause pop eye or this can be a result of a bacterial infection and other serious medical issues can also cause pop eye in Goldfish.

Pop eye is quite easy to see in all types of Goldfish. There will be noticeable swelling in either one or both eyes, maybe a discolored eye or a cloudy eye.

You may see that the eye is bloodstained or that there is damage to the cornea. With proper treatment, most cases will allow your fish to live a healthy and long lifespan of up to 10 years of age.

How To Treat A Bubble Eye Goldfish With A Popped Eye Sack!

Your first move for treatment is always to move any infected fish to a quarantine tank where they can be closely monitored and to keep them from infecting other fish in the case of a bacterial infection. Antibiotic treatments and aquarium salt help speed up the recovery time.

Perform water changes much more often than usual to help your fish recover and make sure the parameters of the water tests are well within the range they should be with a temperature of 50 to 75 degrees F, a water hardness of 5 to 19 dKH, and a water pH level of 6.5 to 7.5.

You can use broad-spectrum specialty antibiotic fish food to treat the eye from the inside out just as humans take antibiotics by mouth.

It’s also beneficial to treat the quarantine tank with antibiotics as well. Since Bubble Eye Goldfish don’t have a dorsal fin, they aren’t the strongest of swimmers and they require about 10 gallons of space in a fish tank because of this.

Larger fish tanks not only give your fish more room to swim, but they also promote good health with less food waste and fish waste that can cause bacterial infections in fish.

You can place a video call with a veterinarian for a diagnosis at a nominal fee if you are not sure if your fish has pop eye, so he can guide you in the treatment.

Will A Bubble Eye Goldfish With A Popped Eye Sack Die Soon?

The underlying cause of the popped eye sack will determine how quickly your Goldfish will recover or if he will. If this condition is caused by environmental issues, it will eventually resolve itself and your fish will live to be old and healthy.

If it’s because of a serious bacterial infection, a metabolic issue, or kidney disease, your fish may not be able to live.

Most often, it is an environmental issue if both eyes have popped eye sacks in a fish and your Goldfish will recover from this with proper care in a quarantine tank.

However, the affected eye will not appear the same as it did beforehand and it can be slightly misshaped or become larger or smaller after healing, making him look imbalanced.

Adding aquarium salt in the tank with the affected fish can help to heal pop eye from environmental issues.

The antibiotic treatments for a fish with an infection should be used both in their food and in the water to treat the quarantine tank, such as erythromycin, ninocycline, trimethoprim or sulfadimidine for pop eye infections.

It’s beneficial to do water changes every week and monitor the water tests to stay in the correct parameters daily with a temperature of 50 to 75 degrees F, a water hardness of 5 to 19 dKH, and a water pH level of 6.5 to 7.5.

Is A Bubble Eye Goldfish With A Popped Eye Sack In Pain?

The beginning stages of pop eye may not be as painful, but as the eye sack swells out more, it makes for a very painful experience for your Goldfish.

The pressure behind the eye builds in strength as the eye protrudes outward more and more. If treatment is not given soon, your fish may actually go blind or die if it’s caused by infections.

Adding salt to the quarantine tank will help to soothe the eyes of your Goldfish. It will also help to reduce the pressure behind the eye, which will also give him great relief.

Remember not to change all the water in the tank while adding aquarium salt, but change only one-quarter on a weekly basis, then retest the water conditions and adjust them as necessary.

You can also feed a little less food than normal in the quarantine tank so there will be less waste in the water. This will also speed up his recovery time by helping the water to stay cleaner and free of additional bacteria.


The best idea is to take care that your Bubble Eye Goldfish popped eye sack never occurs at all as it is painful and can take several months to recover from it. Keep this type of species in an aquarium with 10 gallons of water for each fish so they are not overcrowded. Keep up with your water changes and monitoring and remove any items that can harm your Goldfish’s sensitive eyes in the tank, because the sacks are actually in his line of vision and he can bump into items in the tank.
