After a long time we could finally import some of the beautiful Hyphessobrycon haraldschultzi from the Rio Araguaia in Brazil. The animals are clearly slimmer than serpa tetras (H. eques, “serpae”, “minor” etc.). The coloration is more reminiscent of H. amandae, because the red is – unlike serpa tetras – not a rich blood red […]
The Serpa Tetra, also called the Callistus Tetra (Hyphessobrycon eques, formerly known as H. callistus or H. serpae), is the little man’s piranha. Just like piranhas, serpa tetras have an irresistible urge to bite the fins of other fish. And they constantly want to test out who is the stronger. This makes many exciting observations […]
In 1915 the scientist Carl Eigenmann described a new tetra genus, which he named Megalamphodus. Type species is M. megalopterus, an aquaristic very well known species: the Black Phantom Tetra. In 1997 Megalamphodus became a synonym of Hyphessobrycon. Of the remaining species assigned to Megalamphodus in 1915 (ecuadoriensis, eques, heteresthes, melanotus, micropterus), only the Serpae […]
The Serpae tetra is one of the most popular tetras at all. This is doubtless due to its intensive red coloration. In respect of the behaviour one cannot trust them too far. They have the nasty tendency to bite off pieces of finnage from other fish, also from conspecifics. From a scientific point of view […]

Red fish always attract interest amongst hobbyists, especially the intensively red coloured ones. Five years ago when we received the first animals of this tetra by the name of “Hyphessobrycon serpae – the real one” (wildcaught from Rio Araguaia), we were immediately enthusiastic, too. At first sight (still inside the transport bag) these tetras looked […]
