Description
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.
Fantails are an American breed of goldfish, with egg-shaped bodies and a double tail. They share many similarities with the Japanese Ryukin breed but have a shallower back and a longer body overall.
These are calicos around 1.5-2" long.
