Hyphessobrycon sp. Junior. Synonym: Hyphessobrycon robustulus, H. pandurini. Junior Tetra, Pandurini tetra.

Junior Tetra, Hyphessobrycon sp. “Junior” – This is a beautiful little 1” undescribed tetra species from Peru. It was originally collected by the younger (or junior) member of the father and son team of Peruvian fish exporters, Jesus Victoriano Panduro Pinedo and Noronha Jorge Luis Panduro Pinedo, at the same location that Apistogramma panduro hails from in the Rio Tamishiyacu. This original collector’s name has led to the fish being called Hyphessobrycon sp. “Junior Pandurini”, Hyphessobrycon sp. “Pandurini”, or even incorrectly Hyphessobrycon pandurini. Mostly, now you find the simplified name Hyphessobrycon sp. “Junior” being used. Occasionally, you find this fish as Hyphessobrycon robustulus, but I don’t feel this fish really matches the original description of that species. Regardless of what name you use, each gender of this species has its own color scheme, which makes them extremely easy to tell apart. While both males and females share a silver body, a black spot on the caudal fin, and a touch of gold around the eye, the color of the fins differ dramatically by sex. The males have red tinging around the dorsal, anal, adipose fins, and the lobes of the tail fin. A little of that red blushes the belly of the male, just above the anal fin insertion, and along the back, just forward of the dorsal fin. The female possesses fins that are yellow. Every fin that is red in the male is yellow in the female, aside from the adipose fin, which is clear in the female. They are a pretty peaceful shoaling species, easy to care for, and make fine community fishes.
