Etymology

Megalamphodus: from the Ancient Greek μεγαλάμφοδος (megalamphodos), meaning 'with spacious ways'. Eigenmann did not explain the name, but it probably refers to…

Distribution

Known only from the rio Negro basin in Amazonas state, Brazil, plus the rio Nhamundá, a smaller tributary drainage which enters the Amazon downstream of its co…

Habitat

Mostly inhabits sluggish tributaries, side arms and forest lakes, and often associated with submerged woody structures such as roots, fallen branches, overhang…

Aquarium size

An aquarium with base dimensions of 90 ∗ 30 cm or equivalent should be the smallest considered.

Maintenance

Choice of décor is not especially critical although it tends to show better colouration when maintained in a well-furnished set-up with live plants and a dark …

This species is an opportunistic omnivore by nature.

The stomach contents of wild specimens from the rio Padauari were composed of fruit remains and aquatic insects with the former constituting 99% and latter 1% of all items consumed.

Stomachs of individuals from igarapé Água Boa contained 2.5 % ants (Hymenoptera (Formicidae), 20% terrestrial insects (Ephemeroptera: Baetidae and Diptera: Chironomidae), 53.3% fruit remains, 19.5% fish scales and 4 % elmid beetles.

In the aquarium it is easily-fed but the best condition and colours offer regular meals of small live and frozen foods such as bloodworm, Daphnia, and Artemia alongside good quality dried flakes and granules, at least some of which should include additional plant or algal content.

Submerged pieces of fresh fruit will also be grazed but should only be left in the aquarium for a few hours.

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.

Behaviour and compatibility

Generally peaceful making it an ideal resident of the well-researched community aquarium, although adult males are territorial to an extent and this behaviour …

Sexual dimorphism

Males grow noticeably larger and are more intensely-coloured than females. In adult males the dorsal, pelvic and anal fins are highly extended, while adult fem…

Reproduction

Egg scatterer exhibiting no parental care.

Notes

One of three similar-looking species most commonly-referred to as the 'bleeding heart' subgroup, the other two being H. erythrostigma and H. pyrrhonotus. All p…
