Aequidens latifrons


Aequidens latifrons or the platinum acara, is a species of fish in the family Cichlidae in the order Perciformes.

Distribution[edit]

It is found in South America.

Description[edit]

Males can reach a length of 17 centimetres (6.7 in) total in length.[1] It has a stocky body with a bluish-grey colouration. It has lighter speckles across the scales, with relatively long fins. It is similar in appearance to the blue acara.

Spawning[edit]

The platinum acara spawns several times each year. As with most cichlids there are frequent quarrels between partners. The female cleans a stone carefully and lays eggs on it afterward. They are attached to one another, resembling a pearl necklace. As they begin to increase in size the stone is completely covered by them. The female fans them with her body and pectoral fins. Once the fry have emerged and can swim independently they surround their parents in a great shoal.[1]
