The Orange Zebra Otocinclus Catfish, known scientifically as Hypoptopoma sp. "Peru Orange", is a vibrant and somewhat uncommon species in the aquarium trade, originating from the freshwater bodies of Peru. This small catfish is celebrated for its striking coloration and the unique, eye-catching patterns it displays, making it a favorite among enthusiasts who enjoy exotic and colorful aquarium inhabitants.

This particular species of Otocinclus exhibits a rich, orange hue interspersed with darker vertical stripes, giving it a zebra-like appearance that stands out in any aquarium setup. The body of the Orange Zebra Otocinclus is more rounded compared to other Otocinclus species, with a flat belly that aids in its ability to cling to smooth surfaces in the aquarium. They have large, expressive eyes and a mouth adapted for scraping algae from surfaces.

In captivity, the Orange Zebra Otocinclus thrives in conditions that mimic its natural riverine habitat. It prefers a tank with plenty of aquatic vegetation, driftwood, and rocks, which not only provide surfaces for algae growth but also create hiding spots for this sometimes shy fish. They are best kept in well-oxygenated water with a gentle to moderate current and a temperature range that mimics tropical conditions.

Socially, the Orange Zebra Otocinclus is a peaceful species that does well in community tanks. They are not aggressive and can coexist harmoniously with other small, peaceful fish and fellow Otocinclus. Keeping them in groups is recommended as they are naturally social creatures, and living in a group helps reduce stress and promote natural behaviors.

Diet-wise, the Orange Zebra Otocinclus primarily feeds on algae and biofilm, which it grazes from hard surfaces in the tank. Supplementing their diet with algae wafers and blanched vegetables like zucchini or cucumber can ensure they receive adequate nutrition, especially in newer tanks where algae may not be sufficiently established.

Breeding the Orange Zebra Otocinclus in captivity can be challenging, as their reproductive habits are not well-documented, and replicating the precise conditions conducive to spawning is difficult. However, maintaining excellent water quality, a balanced diet, and a stress-free environment are general factors that could encourage breeding behaviors.

Overall, the Orange Zebra Otocinclus is an intriguing addition to any aquarium, especially for those looking to add some vibrant color and unique patterns to their aquatic setups. Its peaceful nature and role as an algae eater make it a valuable and beautiful member of community tanks.
