The Dark-edged Splitfin (Girardinichthys multiradiatus) is a species of fish in the Goodeidae family. It is endemic to Mexico.

Giradinichthys multiradiatus is a livebearing fish. It is considered to be one of the most difficult fish to successfully keep and breed in aquariums. This is a notoriously challenging fish even to the most experienced, talented, and dedicated livebearer enthusiasts.

G. multiradiatus is a cold water fish from the mountains of Mexico. The species is incredibly temperature sensitive. If water is too cold all offspring will sex out male. If water is too hot, females will birth their first brood of only 1–3 fry and then die shortly thereafter, which makes it very difficult to maintain a colony. This fish is notoriously challenging. It is also a primarily herbivorous species and requires a great deal of vegetable matter in its diet.

G. multiradiatus is a very beautiful fish. Females reach about 3 in and males maybe 2.5 in. The species is commonly called the "golden sailfin goodeid" to due the extended fins and exceptional of the male. Due to the rarity of this fish, auction prices can reach upwards of US$100 for a single pair. They are very difficult to find even if you do have the money. And if you do find them and you do win an auction for them, it is very likely they will just die shortly after arriving at your home. Very few hobbyists are able to successfully keep and breed this species.

This fish was successfully kept and bred for many years by Karma Farm, but they are no longer open.
