hoplios

Hoplios are a genus of small, colorful fish belonging to the family Characidae. They are native to freshwater habitats in South America, particularly the Amazon Basin and surrounding river systems. These fish are known for their vibrant coloration, often featuring stripes or spots that can vary in intensity and pattern depending on the species and their environment.

Members of the genus Hoplios are typically schooling fish, and it is generally recommended to keep them in groups of six or more to encourage natural behaviors and reduce stress. They are omnivores with a diet that can include small invertebrates, algae, and plant matter. In aquariums, they readily accept commercial flake foods, pellets, and live or frozen foods such as brine shrimp or daphnia.

The size of Hoplios species varies, but most remain relatively small, making them suitable for appropriately sized community aquariums. They generally prefer well-oxygenated water with moderate to strong flow, and a planted environment that mimics their natural riverine habitats. Their peaceful nature allows them to coexist with other small, similarly tempered fish. Reproduction in captivity can occur, with the fish laying eggs that are typically fertilized externally.
