The main predators of zebrafish are snakeheads and freshwater garfish. Other predators include catfish, knifefish, spiny eels, Indian pond heron, and common kingfisher. Zebrafish show alarm in response to visual and olfactory predatorial cues. Anti-predator behavior is also triggered by injury pheromones. Alarm behaviors include increased agitation, aggression, and decreased feeding rates. Zebrafish have three pigment cell types that contribute to their stripes. One of the pigment cells, dark blue melanophores, can be altered in response to stimuli. This is believed to help zebrafish evade potential predators.
