Appears to be an exclusive inhabitant of blackwater environments.

In the rio Negro system it inhabits so-called igapó and igarapé habitats characterised by thick, often overhanging, riparian vegetation and substrates covered in fallen branches, tree roots and leaf litter.

The water is typically acidic, of negligible carbonate hardness and conductivity and stained brownish due to the presence of humic substances released by decomposing organic matter.

The Negro has a substantial floodplain and the water level can rise by up to 15 metres during the annual wet season.

During the period of inundation small fishes such as C. strigata move upstream within the river's tributaries and then laterally into the flooded forest itself to feed and reproduce, before returning to the tributaries when the water falls.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Anything worth adding

Describe what you saw, or which part of the source says this.

Aquarium size

Surface dimensions of 75 ∗ 30 cm or more are recommended since this species should be maintained in numbers (see 'Behaviour and Commpatibility').

Maintenance

Should ideally be kept in a heavily-planted set-up, preferably with a dark substrate and some patches of floating vegetation around which the fish will tend to…

Water conditions

Not written yet

Diet

Primarily a predator feeding on terrestrial and aquatic invertebrates and other zooplankton taken at or near the water surface in nature. In the aquarium it wi…

Behaviour and compatibility

Very peaceful but does not make an ideal community fish due to its small size and rather timid nature. In a community it's best kept with similarly-sized, peac…

Sexual dimorphism

Some specimens do grow larger and become rounder-bodied than others, and presumably these represent adult females.

Reproduction

Unrecorded.

Notes

C. strigata is an enduringly popular species in the aquarium hobby but is not bred on a commercial basis with all fish offered for sale collected in the wild. …
