Spikedace (Meda fulgida) is a small (up to 8 cm) fish that persists in a restricted distribution in the upper Gila River basin of Arizona and New Mexico and is being actively managed through population augmentations and translocations. They are found in sand- and gravel-bottomed, shallow, clear streams with permanently flowing water. The primary threat to this species is thought to be non-native fishes that compete with or prey on Spikedace.
