Bubble Eye Goldfish

Bubble Eye goldfish are a “fancy” variety, which is characterized by fluid filled sacs beneath the eyes. Bubble Eyes lack dorsal fins and have double tail fins. They can be found in gold, red, black, white and calico colors. The fish can reach eight inches long and the bubble sacs grow with the fish, sometimes occluding the fish’s vision.

Bubble Eye goldfish are as cheap and readily available as any fancy breed, but are not recommended for new fish owners. The vulnerable sacs are easily damaged and require care to reduce risk. The contents of the tank must be screened to ensure no sharp or abrasive surfaces such as sharp rocks or even filter fixtures can threaten the fish. If the sacs are punctured, the water must be kept especially clean and topical medicine may be required. A punctured sac can heal, but will almost always scar.

Bubble Eye goldfish must also be kept with slow and peaceful fish due to the vulnerable eye sacs. These can get large enough to hinder the fish’s ability to swim and thus the fish will not compete as well. Other bubble eyes, telescopes and celestial eyes are particularly suitable.

Bubble Eye goldfish prefer still waters. They require a minimum of ten gallons of water, and up to fifty gallons may be optimal for large bubble eyes. This breed is best in slightly warmer water, seventy six to seventy eight degrees.

However, at these temperatures it is important to properly aerate the water. With proper use of air stones and bubble walls, bubble eyes can be healthy in water up to ninety degrees.

Water changes must occur often to keep the nitrate levels below forty parts per million.

While all goldfish are vulnerable to poor food choices, bubble eye goldfish are especially vulnerable due to the breed’s large belly. The fish have best results from sinking food and a variety of fruit and vegetables. Floating food can lead to air ingestion, and bubble eye goldfish are even more vulnerable to this than most goldfish. This can lead to constipation and swim bladder problems. The fish will have trouble swimming upright and will spend time near the surface or bottom. These symptoms can also be caused by poor water cleanliness. Swim bladder problems should be treated with a fast of twenty four hours followed by a diet of frozen green peas for several days. If processed, floating food must be used, it should be allowed to soak up water before being fed to the fish.
