Overview

This armoured catfish, a cousin of the Corydoras, is recognised by the black and white bands on its tail fin. Every fish sold is wild-caught: fragile on arrival, they become very hardy once acclimatised.

Scientific name
Dianema urostriatum (Miranda Ribeiro, 1912)
Classification
Siluriformes › Callichthyidae
IUCN Red List
Least concern (LC)

Natural habitat

Brazil: Amazon basin

Observations (GBIF) and localities Native countries Rivers and lakes

It lives away from the main channels, in creeks, slow tributaries, floodplain lakes and pools. It breathes air at the surface.

Behaviour

Very peaceful, it leaves even the smallest companions alone (only tiny fry risk being swallowed). It lives with tetras, peaceful cichlids, Corydoras and small Loricariidae, in a group, as it is gregarious. An omnivore, it accepts sinking pellets and frozen prey, and often comes up to feed at the surface.
