The Bubble Eye is a small variety of fancy goldfish with upward pointing eyes that are accompanied by two large fluid-filled sacs.It is a dorsal-less fish, and good specimens will have a clean back and eye bubbles well matched for colour and size. The bubbles are fragile and the fish should be kept separately from boisterous types and away from sharp tank decor, although the bubbles will regrow if punctured. Given proper accommodation, the bubbles do not disadvantage the fish and they become very tame. It is known as suihogan in Japan.
Description
The Bubble Eye normally has an evenly curved back that lacks a dorsal fin. The pair of large pouches of skin attached under its eyes jiggle as it swims.Bubble Eyes have metallic scales and they are similar to the celestial eye goldfish.The eyes of the Bubble Eye goldfish are normal in the young fry, but will start to develop eye bladders three months after hatching.Like ranchu,the bubble eye goldfish lacks in dorsal fin and has a double tail. They normally grow up to 6 to 8 inches in length.
Coloration
Bubble Eyes come in many color patterns such as red, red-and-white, black, gold and calico.
Social behaviors
Goldfish are very social animals and thrive in a community. Not only are they a great community fish but they are great scavengers as well. It is really not necessary to add other scavengers or other bottom feeders to the aquarium when you have goldfish.
Special care
Bubble eyes are inexpensive and they are very commonly seen as other goldfish. It is not recommended for beginners because the eye sacs can get punctured if it is not handled carefully.This goldfish requires a special aquatic environment because they are relatively poor swimmers due to their impaired vision, and cannot compete with more active goldfish. So there is a chance of losing their food to other active fishes. Their "bubbles" can be easily sucked into the filter intake. These bladder-like swellings can also be easily damaged by any sharp-edged rocks and tank decorations.Bubble eye and fancy goldfish varieties may remain healthy up to 90°F.
This is another dorsal less breed, but this breed should have no head growth. this strange breed has a large fluid-filled bubble under each eye that wobbles as the fish swims. the bubbles (from bubble to bubble) can be as wide as the fish is long, which is an awesome sight in a large adult Bubble-eye. The body is long and torpedo shaped with long flowing double tail fins. the bubble-eye will need a carefully arranged aquarium free from any sharp projections. It is not recommended for beginners.The bubble eye is comparatively rare in UK. It is a dorsal-less fish, and good specimens will have a clean back and eye bubbles well matched for colour and size. The bubbles are fragile and the fish should be kept separately from boisterous types and away from sharp tank decor, although the bubbles will regrow if punctured. Given proper accommodation, the bubbles do not disadvantage the fish and they become very tame.
In the Far East, bubble eyes with small bubbles and celestial type eyes are known as frogheads or toadheads. There is also a type with double bubbles, one just under the eye on each side (like the traditional, single bubbles) and one just below and to the rear of the mouth on each side.
THE STANDARD
The bubble eye standard is as follows:
- Depth of body to be greater than 1/2 of body length
- Eyes to have a sac under and around the sides of each eye
- Dorsal fin to be absent
- All other fins to be paired
- Caudal fin to be divided and forked
- Extremities of fins to have a rounded appearance
- Minimum length of body to be 5.5 cm (2¼ inches)
The fish should be bright, alert and well balanced. The body should be short not elongated, with smooth contours and showing no sign of a dorsal fin. The caudal fin should be well divided. The eye sacs should be well developed and evenly matched.
The colour may be metallic (self-coloured or variegated in a pleasing pattern and similar on each side) or calico. Metallic colours should appear as burnished metal, extending into the fins. Calico fish should have a blue background with patches of violet, red, orange, yellow and brown, spotted with black.
Ideal profiles are illustrated below:
THE FISH
Notice that all the fish illustrated on these two
pages have nicely balanced eye sacs, matching each other in size and shape. It is fairly common to see fish with one eye sac larger than the other; this does not affect the fish at all, but makes it appear unbalanced.

Metallic bubble eyes
A mature adult, self-coloured yellow metallic fish, close to the standard, but with rather long tail lobes, although it is nicely self-coloured, lemon yellow being unusual in this type. It was shown at BAS 1999.
A young adult, variegated red-orange/silver-white fish with the long finnage and slender body of a Far Eastern lineage; its eye bubbles could ideally be slightly larger but they are well matched in size. It was shown at BAS 2000.
Red bubble eye shown at BAS 2003, with long tail lobes and a somewhat slender body.
Red bubble eye shown at BAS 2005, with shorter tail lobes and a deeper body.
