Tuxedo Red Koi GuppyWith sunset hues and a graceful dorsal fin, the Tuxedo Red Koi Guppy turns heads in any freshwater aquarium it is in. Active when kept healthy and its colors just jump out. A hard water fish in nature and while it may manage in soft and or acidic conditions, long term maintenance should be provided for guppies in moderately hard or harder water. Unfussy, though a planted tank with floating vegetation is appreciated. Strong currents should be avoided.
