Kohaku Koi Guppy

Guppies have a well-deserved legendary status as aquarium fish and are even well known outside the hobby. The enormous variability of these little livebearers has transformed them from short-finned wild fish with a variety of coloured spots, to a whole host of selectively bred forms in a range of fin and colour types. Fancy guppies are akin to any pedigree animal and are not the tough bullet-dodging fishes that earned a reputation for hardiness. Like domestic dogs they’re all the same animal, but nobody expects a chihuahua to pull a dog sled. The real power of these fishes is their ability to breed and adapt, even these highly bred forms will happily cross breed until your aquarium is home to smaller spotted fish that can tolerate all manner of conditions that would stress their aristocratic ancestors.
