Uaru amphiacanthoides
An Amazonian cichlid with a near-triangular body and a large dark blotch on each flank; juveniles are quite differently marked, speckled with white. It needs warm, soft water, and its fry feed on the parents' skin secretions.
Uaru amphiacanthoides occurs along the Amazon-Solimões from the Japurá to the Tapajós and in the middle and lower Negro basin. Adults are yellowish-brown with a large dark blotch, while juveniles look entirely different, speckled with white. FishBase records a maximum of 25cm SL and Seriously Fish 25.4cm, so the sources agree closely. Seriously Fish gives a 120 x 45 x 37.5cm tank (200 litres) for a pair, at 27-30C, pH 6.0-7.0 and soft water up to 5 dGH. Those high temperatures limit which species can share the tank. It is omnivorous in the wild but appears primarily herbivorous in captivity, so blanched vegetables should be offered regularly. It is peaceful for its size and can be combined with tetras, angelfish and eartheaters such as Geophagus and Satanoperca. It spawns on a flat rock or piece of bogwood, and the young feed from the parents' slime coat much as discus fry do.

About 120 x 45 x 37.5cm (200 litres) for a pair. Arrange bogwood and include a flat stone as a spawning site.
27-30C, pH 6.0-7.0, soft water up to 5 dGH. Maintaining warm, soft water is a precondition for keeping it.
Peaceful, but tank mates must tolerate the elevated temperature. Tetras, angelfish and eartheaters are suitable.
In captivity it favours plant matter. Base the diet on vegetable-based foods with blanched vegetables, and keep animal protein modest.
Spawns on a flat rock or piece of bogwood. The fry feed from the parents' slime coat, as discus fry do.
Wild-caught fish demand soft, acidic water closely matching their habitat; captive-bred stock is less demanding.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Uaru is 27〜30℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Uaru is 5-8 years. With proper care and nutrition, they can live a long and healthy life.
Uaru typically reaches 25cm as an adult. Size may vary depending on care conditions and individual genetics.
Uaru feeds on: Vegetable-based prepared foods, blanched vegetables. Aim for a balanced diet with appropriate feeding frequency.
