Physical Description

The Bubble Eye Goldfish is beautiful in a very grotesque sort of way. You will either love it the moment you see it or you will absolutely hate it. Most people find the presence of huge bubbles under the eye disturbing. These bubbles are filled with a very delicate liquid. The other unique feature of its eyes is the placement. This species of goldfish has eyes that point upwards. They are not as round as other species but are slim with smooth backs. They have a pair of anal, ventral and pectoral fins. This species doesn't have dorsal fin. Caudal fins are divided and forked.

Color Varieties of Bubble

The Bubble Eye Goldfish occurred in red and white, plain red, red and black, and sometimes even in blue and brown, spotted black and burnished metal.


The Bubble Eye Goldfish is comfortable with minimum 20 to 30 gallon water tank. This fish are fragile so you will have to make sure that there are no sharp objects such as ornaments, plastic plants inside the tank and even the tubes of the filter should be covered with a sponge. You will also have to be extra careful while transferring this fish. You should try and avoid putting different species in the same tank as a Bubble Eye Goldfish. Their poor eyesight might cause them to starve to death if there are faster and quicker fish in the tank.


This fish can survive with a temperature of 65 - 72 degrees F (18 -22 degrees C).

Water Condition:

The tank water conditions should be maintain a pH level of 6.5 - 7.5 and dH of 4 - 20

Moving Level in Water:

Special Care:

Housing this fish can be quite challenging due to the presence of delicate bubbles under its eyes. You have to take regular care of the fish as the sensitive bubbles may break easily. In most cases, new bubble will not grow. In some cases, they grow again. And in the time between the growth of new bubble, the fish may be affected by infection.


Bubble Eye Goldfish aren't fussy eaters and they eat all kinds of fresh, frozen, and flake foods. To maintain a good balance, give them a high quality flake food like brine shrimp (either live or frozen), blood worms, Daphnia, or tubifex worms as a treat.It is usually better to feed frozen/dried foods as opposed to live foods to avoid parasites and bacterial infections that could be present in live foods. You can even feed vegetables like lettuce and cucumber. You will have to choose their diet carefully. Due to the bubbles under their eyes, they find it very difficult to find foodthat sinks quickly or is too small. It is perhaps a good idea to drop the food in the same place everyday or use large and slowly sinking pellets. Better solution is to teach your Bubble Eye Goldfish to accept food from your hand.


It is very difficult to breed this fish. They lay up to 1000 eggs. The bubble on the fish will start to grow at the age of 6 to 7 months. For more info, refer Breeding.
