Distribution

Brazil, Paraguay and Argentina. You're unlikely to see any wild fish for sale though. Due to its popularity, it's commercially bred in huge numbers for the tra…

Habitat

Mostly inhabits clear water rivers that feed the famous Pantanal wetlands. Unlike in the often murky waters that flow through the Amazon rainforest, aquatic ve…

Aquarium size

It's a particularly active species and given its adult size deserves a tank of at least 90 ∗ 38 ∗ 30 cm36 ∗ 15 ∗ 12 in - ~103 litres~27 US gal.

Maintenance

Quite an adaptable species that will thrive in most well maintained tanks, although it doesn't like very brightly lit or sparsely decorated environments. It lo…

Water conditions

Temperature: 22 – 26 °C72 – 79 °F pH: Due to the great range of water conditions between the wet and dry seasons in its natural waters, it's quite unfussy and …

Diet

Easy to feed. It will readily accept just about anything offered. For the best condition and colours offer regular meals of small live and frozen foods such as…

Behaviour and compatibility

A decent, albeit robust choice for the 'general' community tank, where it will add plenty of movement. Sedate species such as anabantoids or dwarf cichlids can…

Sexual dimorphism

Female is a rounder bodied fish when inbreeding condition.

Reproduction

Can be spawned in a similar way to other species in the genus. You'll need to set up a separate tank in which to do so, if you want to raise fry in any great n…

Can be spawned in a similar way to other species in the genus. You'll need to set up a separate tank in which to do so, if you want to raise fry in any great numbers. Something around 18" x 12" x 12" in size is fine. This should be very dimly lit and contain clumps of fine-leaved plants such as java moss or spawning mops, to give the fish somewhere to deposit their eggs. Alternatively you could cover the base of the tank with some kind of mesh. This should be of a large enough grade so that the eggs can fall through it, but small enough so that the adults cannot reach them. The water should be soft and acidic in the range pH 6.0-7.0, gH 1-10, with a temperature of around 26.5 – 29 °C80 – 84 °F. A small air-powered sponge filter bubbling away very gently is all that is needed in terms of filtration.

It can be spawned in a group, with half a dozen specimens of each sex being a good number. Condition these with plenty of small live foods and spawning should not present too many problems.

Alternatively it can be spawned in pairs. Under this technique the fish are conditioned in male and female groups in separate tanks. When the females are noticeably full of eggs and the males are displaying their best colours, select the fattest female and best-coloured male and transfer them to the spawning tank in the evening. They should spawn the following morning.

In either situation the adults will eat the eggs given the chance and should be removed as soon as eggs are noticed. These will hatch in 24-36 hours, with the fry becoming free swimming a 3-4 days later. They should be fed on an infusoria-type food for the first few days, until they are large enough to accept microworm or brine shrimp nauplii.

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 profileFor example, the Behaviour and compatibility section already says this.
