Characidae

Probably restricted to parts of the upper Amazon basin[1] in Peru and the Rio Araguaia in Brazil.

The Araguaia flows through several Brazilian states and is thought to have numerous sources due to the high number of tributaries that empty into it. It’s likely then that this species[2] can be found existing in various types of habitat[3], from wetlands with luxuriant growth of underwater plants to jungle streams with dense marginal[4] vegetation but little in the way of aquatic[5] plant life.

Although listed by some sources as only attaining 1.4″/3.2cm it definitely grows larger. Expect it to reach at least 2.4″/6cm, with 3″/7.5cm not being that uncommon.

A 24″ x 15″ x 12″/60cm x 37.5cm x 30cm/70 litre[6] tank[7] is suitable for a small group of these. Ideally keep it in higher numbers in a bigger tank[8] though.
