What Uaru look like

Uaru amphiacanthoides exhibits a distinctive deep, disc-like, oval body shape, reminiscent of a massive discus, with a maximum adult size ranging from 2 to 10 inches. The coloration is primarily a pale creamy-tan, which is strikingly contrasted by a prominent, dark black wedge or teardrop-shaped blotch located on the lower rear flank, serving as a key identification feature. This species possesses a laterally compressed body, which aids in maneuverability within its natural habitat. Sexual dimorphism is subtle, with males typically exhibiting slightly larger sizes and more pronounced coloration during breeding displays. Defensive adaptations include a robust body structure and the ability to blend into its environment, while the presence of an adipose fin and a well-developed lateral line system enhances sensory perception in its murky Amazonian waters.

Behavior & temperament

Uaru amphiacanthoides is generally a peaceful species, often found in small groups, though it can exhibit solitary behavior when establishing territory. This cichlid primarily inhabits the mid to lower water column, favoring areas with dense aquatic vegetation. Breeding behavior involves the laying of eggs on flat surfaces, where both parents exhibit care for the offspring, making them mouthbrooders. Their temperament is generally calm, but they can display territorial aggression during breeding periods, particularly towards conspecifics.

Diet & feeding

In the wild, Uaru amphiacanthoides is primarily herbivorous, consuming a diet rich in plant matter, including algae and detritus. In captivity, they require a diet high in vegetable matter, such as spirulina flakes and blanched vegetables, to maintain optimal health.

Behind the name

Uaru (from the indigenous Tupi language, meaning 'to eat') and amphiacanthoides (from Greek 'amphios' meaning 'both sides' and 'acanthus' meaning 'thorn', referring to the spiny structures on the fish).
