Type locality is ‘Rio das Mortes, some 100 km before its confluence with the Braço Maior of the Rio Araguaia (the western border of the Isla do Bananal). State of Mato Grosso.’

The das Mortes is a principal tributary of the Araguaia, itself the major affluent of the rio Tocantins within the lower Amazon basin in central and western Brazil, although the full range of H. amandae within the Araguaia system is unclear.

This species is also traded as ‘blue flame’, ‘blue-red’, and ‘Colombian red fin’ tetra, and was misidentified as H. ecuadorensis for several years prior to its description.

Within the genus it appears to be most closely related to the Costa Rica endemic H. savagei Bussing, 1967 but differs in a number of characters as fol…

Metynnis lippincottianus is occasionally seen for sale, sometimes under the name of "Silver Dollar". It is easily distinguishable from m. argenteus and m. hypsauchen (which are more commonly sold as Silver Dollars) by its spotted pattern, hence the common name. M. lippincottianus shares a common name with m. maculatus but the two can be distinguished as the spots on m. maculatus are more pronounced.

Silver dollars are common and popular fish in the hobby. They are related to piranh…

L. taeniata is the largest-growing and second most widely-distributed member of the genus although it’s a rarely-seen in the aquarium trade.

It can be distinguished from all congeners since it uniquely possesses 5 lateral scale rows between the lateral line and dorsal-fin origin (vs. 4 or 6–8 in the remaining species).

Omnivorous and will accept most foods offered, with the stomach contents of wild specimens varying on a seasonal basis but mostly comprising insects and insect larvae (orders Trichoptera, Hemiptera, Homoptera) plus some terrestrial fruits and even scales of other fishes (Sánchez et al., 2003).

In the aquarium offer live Daphnia, Artemia, Moina, bloodowrm, etc., vegetable matter in the form of blanched spinach, lettuce, cucumber, fruit, algae wafers, etc., and good quality, sinking dried foods.

A biotope-style set-up could consist of a sandy substrate, piles of smooth rocks and driftwood roots and branches, some of which should penetrate the water surface.

Aquatic vegetation can be included if you wish but is likely to be eaten.

This species is also referred to as ‘black-anded leporinus’, ‘striped leporinus’ and ‘eight-banded leporinus’.

Young specimens are often traded for aquaria without warning as to their potential size and requirements, and as a result it’s fairly ubiquitous in public aquarium displays.

This species is widely-distributed in the Río Orinoco system in Brazil, Colombia and Venezuela plus coastal drainages in Guyana, Suriname and French Guiana including the Essequibo and Mazaruni.

Type locality is ‘Palital, Estado Guárico, Venezuela’ which appears to correspond to a wetland called Esteros de Palital in the Aguaro-Guariquito National Park of Guárico state, northern Venezuela.

Abramites spp. are separated from other anostomids primarily on the basis of their relatively deeper bodies and presence of a prominent, post-pelvic median keel, a feature unique to the genus.

At time of writing A. eques is the only other species recognised and is native to the Río Magdalena drainage in western Colombia.

It can be distinguished by possession of 13-14 bra…
