Zebra Pleco (Hypancistrus zebra)
…a small species of catfish that is endemic to Brazil where it is found in the Xingu River. Like other catfish zebra pleco are nocturnal and are often found in the bottom, where they feed on algae and small invertebrates. Zebra pleco are sexually dimorphic as males have a larger head and longer interopercular spines than females. Males will also guard the females eggs after they spawn.
Although their conservation status is not evaluated zebra plecos face a serious threat due to the construction of the Belo Monte Dam, which could hinder the water flow of the Xingu river. Zebra pleco are highly sought after in the aquarium trade due to their unique coloration. However, their rarity makes them extremely expensive.
