Bubble Eye Goldfish - Tips and Characteristics

When it comes to fancy goldfish, the Bubble Eye is probably the most exotic of all breeds. Unlike most goldfish varieties, it's not relatively easy to care for, and therefor not recommended for beginner aquarists.

Bubble Eye goldfish have an evenly curved back that lacks the dorsal fin. They have and egg-shaped body that should have no bumps/spikes along the back. Smooth arch from head to the twin tails.

Their upward pointing eyes are similar to the Celestial Eye, with the exception of its two sacs(fluid filled bladders), just under the eyes. The sacs should be uniform in size and well matched color. The bubbles are fragile and if ruptured, the fish can get sick or die. Often sacs can grow back if rupture, but they won't be symmetrical anymore.

These goldfish normally grow up to 6-7 inches in length, being one of the small varieties of fancy goldfish. When young, their eyes are normal, but will start to develop later.

Most Bubble Eyes are available in red, white, orange, yellow or calico. Bright yellow species are very rare.

What else you need to know...

Due to their poor vision, Bubble Eyes can't compete for food with more agile and active goldfish. Their sacs can rupture if you have sharp or pointing objects in your tank. Some types of fake plants may also scratch the sacs.

The sacs or pouches attached under and around the eyes jiggle as the Bubble Eye swims. When taking them out of the water, remember to support the entire head(sacs included) with your hand.

Other popular Bubble Eye variants are the Toad Head with less developed sacs and the Double Bubble which have an additional set of bubbles under their mouths as well.

Mixing

The perfect tank mates for Bubble Eye are similar and slow moving goldfish like Celestials or Black Moors. This way you ensure that they can get their share of food and don't get stressed or hurt by the faster fish.

Don't mix with faster, more competitive single-tails.
