There are several different types of shubunkins based on their tail lengths and shapes, but they all have similar coloration and metallic looking scales. The shubunkin goldfish is another type of slim-bodied, single tailed goldfish with one unique distinction, their beautiful calico coloration. With a good environment, the common goldfish can thrive, live for more than 10 years and grow to over 12 inches in length! So think twice before planning on keeping one of these in a tiny fish bowl. They closely resemble their ancestors, the carp and aren’t as modified (single tail, long-bodied) with all these aesthetics that other species tend to have. Most of us have probably kept one or two of these in a small fish bowl which is a common misconception about these fish.ĭespite being inexpensive, these fish are actually one of the hardiest fish that can survive (but not thrive…) in poorer water conditions. They’re usually sold as feeder fish and are inexpensive. This type of goldfish is often called the common goldfish because, well… they’re the most common type of goldfish you can find out there! These types of fish tend to be much hardier as they aren’t as prone to all of the issues that comes with the shorter bodied fish.īecause of their size and hardiness, they’re often kept outdoors and make GREAT pond fish! Common Goldfish Single-tailed goldfish, in general, tend to look more like their ancestors, which can grow to be quite large. Here’s a list of all of the different goldfish breeds. While all these different breeds are all technically goldfish, they all have their own unique traits and may require special care or larger tank size requirements. I couldn’t have been more wrong! While goldfish and koi originated from the carp family, fish enthusiasts have carefully bred their desired features into all of the different varieties that we see today. Before getting into the Goldfish keeping hobby, I always associated the common feeder goldfish as the only type of goldfish out there.
