Red & White Ranchu Goldfish
The domestic Goldfish is one of the most popular fish kept today, and also one of the very first to be kept indoors. Contrary to dated belief, goldfish cannot be kept in tiny, unfiltered bowls. They should get quite large (about the size of a sweet potato) and live for decades. These are intelligent fish that will come to recognize their owners; the idea that their memory span is only 3 minutes has been disproven by multiple scientific studies. An ideal environment for goldfish is a 30-40 gallon tank with at least 2-3 goldfish, and nice strong filtration.
Ranchu are one of the breeds of goldfish with distinctive fleshy hoods or wen. They have an egg shaped body and a double tail. These ranchu are white with orange splotching. These individuals are around 2″ long.

My Ranchu has been in the tank for six months and is very active. It recognizes me when I approach the tank and swims toward me. The white body with orange spots is striking and the fish seems healthy and happy in a 35-gallon tank with good filtration.

The fish arrived quickly and looks exactly as described. It has a nice fleshy hood and double tail. I’ve kept it in a 40-gallon tank with a filter, and it’s adjusting well to the environment.

I was skeptical about goldfish being intelligent, but this Ranchu has shown clear recognition of my routine. It swims in patterns and seems to respond to the same light cycles. Very satisfying to watch.
