A beautiful species that is very similar to a host of others in the genus, some of which are undescribed. The most frequently encountered of these in the trade is the rosy tetra, H. rosaceus. H. bentosi may also be seen for sale as 'Bentos' tetra' or 'White-tipped tetra'.

As with the closely related Hemigrammus, the taxonomic status of all species in the genus Hyphessobrycon is currently Incertae Sedis, meaning uncertain. The genus is currently used as something of a …

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.

Julidochromis are commonly known as "Julies" in the hobby. Despite being the largest species of Julie this is actually the least aggressive member of the genus. As with other Julies, large water changes should be avoided as it can cause mated pairs to turn on one another.

J.regani may also be seen for sale labelled as Striped Julie or Convict Julie. Several geographical morphs are available. Apparently, the yellower of these are found in shallower water with the darker forms inhabit…

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…

Julidochromis are commonly known as "Julies" in the hobby. This particular species may also be seen for sale as the Chequered Julie. A truly characterful cichlid exhibiting quirky behaviour, it will swim hugging the rock surfaces no matter what the angle is. As with other Julies, large water changes should be avoided as this can cause mated pairs to turn on one another.
Several geographical morphs are available. However, no two species or morphs of Julidochromis should be kept togethe…

Similar in care and appearance to its close relative, the Redhook (myloplus rubripinnis), myleus schomburgkii is easily distinguished by the black vertical bar on the flanks. It is also a smaller adult fish. Despite this, it is sometimes offered for sale marked as a Redhook.

This fish is also variously referred to as the Black-ear Pacu, Disc Pacu and Disk Tetra….

The Redhook is another species commonly sold as a Silver Dollar in the trade. It can be distinguished from those species as the black-trimmed, redis much more obvious than any of the metynnis species. The Redhook is also capable of growing much larger than its Silver Dollar relatives. This species was until recently referred to as myleus rubripinnis and is still widel y referred to as such.

The Redhook is sometimes described as a difficult fish to care for but, given a large enough aquarium, …
