The Hi Fin Platy, also known as the Moonfish or the Southern Platyfish, is a hybrid fin variation of Xiphophorus maculatus platy. Hi Fin Platies were named because of the very tall dorsal fin that extends over their back. There are many different colors and color combinations of this fish. The most common colors are red, yellow, orange, blue, and wag varieties with black tails. They add brilliant colors to the aquarium as well as being very easy to keep, making them a great fish for beginners and accomplished aquarists alike.
The Hi Fin Platy requires a tank of at least 10 gallons that is densely planted with hardy plants like Java Fern and Java Moss. They are very peaceful fish and make an excellent addition to the community tank. Any other peaceful fish can be housed with them.
The Hi Fin Platy is a livebearer and is capable of reproducing at three to four months of age. The male is smaller and more brightly colored than the female, and can be distinguished by his gonopodium. The fry will most often reach maturity in a community tank.
The Hi Fin Platy is an omnivore that will eat commercially prepared flaked foods and algae, as well as freeze-dried bloodworms, tubifex, and brine shrimp.
