Black Tail Koi Kohaku Swordtail (Xiphophorus helleri)

Very Koi-like, tri-color variation of the Swordtail livebearer; red-orange head and caudal peduncle, black tail, opaque body, what's more to say about this neat livebearer?

Like other swordtails, the Koi Kohaku can tolerate a wide range of parameters and diet and will even snack on hair algae in a pinch, similar to other live-bearing species. quality flakes, frozen microcrustaceans and live foods can promote vivid coloration and enhance the red-orange in this fish.

Males may take time to develop sword extensions on their lower tail lobe, but the presence of a gonopodium where the anal fin should be is a sign of its sex.
