Hyphessobrycon notidanos from the upper drainage of the Rio Tapajós in Brazil, which was scientifically described only in 2006, is apparently a quite multicolored animal. So there is the “Red Devil” with much red in the body and blue iris and the “Yellow Devil” with red iris. Both color forms are said to occur together in nature, but they are exported separately. They are really pretty animals, not at all devilish!
In collections from nature there were no specimens over 3 cm length (measured without caudal fin). Characteristic for the species is the pointed, extended dorsal fin of the males, which reaches almost to the adipose fin.
The care of the unfortunately still quite expensive fish is easy and corresponds to that of e.g. king tetras (Inpaichthys kerri). For feeding, the animals greedily accept any common fish food of suitable size. Hyphessobrycon notidanos is completely peaceful and does not damage plants. The water temperature in the wild is around 26°C, a value that certainly deviates occasionally by a few degrees up or down due to weather and seasonal conditions.
For our customers: the “Red Devil” has code 261263 on our stock list. Please note that we only supply wholesale.
Currently we can offer exclusively some top-rarities among the tetra family, all German bred. One of them is Hyphessobrycon piranga, which was introduced in the hobby by Peter and Martin Hoffmann in the German magazine Datz (issue 11/2017) under the unusual name of „Hyphessobrycon sp. non-red devil“. Despite the fact that the new tetra has a lot of red colours it is obviously not identical with the probably still undescribed species that is known as „Red Devil“ in the hobby and that develops inter alia much larger fins. The „non-red devil“ was described officially in march 2018 under the name of Hyphessobrycon piranga. The new species occur from rivers in the upper rio Tapajós catchment.
The males of the pretty species have red fins, while the females remind one a bit in black neons (H. herbertaxelrodi) or H. nigricinctus. In the wild the fish are mature at a size of about 2 cm standard length (without fins), but in the aquarium they will grow a bit larger. The photographed bred ones are about 3 cm long. The photo made by Peter Hoffmann shows a pair of the breeders.
This tetra is a beautiful, easy to keep and very lively fish.
For our customers: the fish have code 261552 on our stocklist. Please note that we exclusively supply the wholesale trade.
