Japanese scientists created a transparent goldfish (besides a transparent frog). The goldfish’s scales are transparent, you can actually see its organs, muscles and even its beating heart. These “see-through” fish can reach the age of 20 and can have a size of about 10 inch and weigh about 5 pounds. Professor Masayuki Sumida from Hiroshima university explains the “Ryukin” fish was created by selecting and breeding.

Transparant goldfish are useful for scientific purposes, offering a realistic alternative for dissections.

The fantail goldfish is a fancy goldfish, but it has more in common with non-fancy varieties.  It can survive and compete successfully alongside common, comet and shubunkin goldfish in ponds and aquariums.  It is also easy to breed, and an ideal fancy goldfish for beginners.

The Black Moor is one of the most beautiful goldfish varieties. It has light wispy fins, black velvet scales, big round eyes, and a nicely proportioned body. Due to the fact it can’t swim fast, its smooth effortless movement is very relaxing to watch.

On top of all that it is relatively easy to keep and is a good goldfish to start with when moving towards fancy goldfish keeping.
