Fancy Goldfish: What to Avoid

First of all I have to confess I do like most Fancy Goldfish but there are a couple of issues with them that I am personally not entirely comfortable with. But first I want to point out that I don't view all Fancy Goldfish in the same way. Some have been bred for hundreds of years and with good breeding there are few deformities and few problems. But there are some which just seem to cross the line and are an adaptation to far. I am referring to the Bubble eye Goldfish

This variety has two large fluid filled balloons, one below each eye. These sacs are very prone to damage, puncture and infection. This is made worse because the fish can't actually see where it is going because its eyes point permanently skywards. The fish also lacks a dorsal fin although this doesn't seem to affect them too much.
They should not be kept with any other fish because they have little defence and are to easily bully and they are unlikely to be able to compete for food. For obvious reasons there should be no sharp objects in their tank not even gravel unless it is well rounded. All in all the fish must have a poor quality of life.
I think that this is an adaptation too far. The choice is yours.

The other thing. That should be considered when buying these fish is that only 2 or 3 % of all the fry born will make good quality fish. The rest are usually culled at an early age mostly because they are born deformed or they don't make the grade. What ever your view on this practice it did at least keep the breeding stock good. Recently there has been a trend to simply selling all the fry regardless of the quality and this has led to a sharp decline in the standard of the various breeds. Even more low quality fish on the market suffering from all kinds of problems but mainly from swim bladder disorder.
If like me you still want to keep fancy Goldfish it is worth going to a reputable breeder and paying more for a good quality healthy fish rather than a misshaped something or other going under the name of Oranda.
When choosing one of these fish there are certain things to look out for in order to avoid buying breeders reject.
