Iberus

Iberus is a genus of small freshwater fish belonging to the family Cyprinidae, commonly known as barbs or minnows. These fish are native to the Iberian Peninsula, which includes Spain and Portugal, and are also found in parts of North Africa. The genus Iberus currently contains only one recognized species, Iberus hispanicus, though historically other species have been assigned to this genus.

Iberus hispanicus, often referred to as the Iberian barb or Spanish barbel, is typically a small, slender fish with a pale, silvery body. They inhabit a variety of freshwater environments, including rivers, streams, and lakes, preferring areas with moderate to fast currents and gravelly or sandy substrates. Their diet consists primarily of small invertebrates, algae, and plant matter.

Reproduction in Iberus hispanicus generally occurs during the warmer months, with females laying small, adhesive eggs on aquatic vegetation or substrate. The young are born relatively small and vulnerable, with growth rates dependent on food availability and water conditions. They are an important component of their native ecosystems, serving as both predator and prey.

The conservation status of Iberus hispanicus varies across its range. While some populations are stable, others face threats from habitat degradation, water pollution, and the introduction of invasive species. Efforts are underway in some regions to monitor and protect native Iberus populations.
