[Ebook] 500 freshwater aquarium fish – Characoids – Red-eyed Tetra (Arnoldichthys spilopterus)

This species is the only representative of its genus. It was first imported into Europe in 1907; since then it has always been available but has never achieved the “greatness” of some other tetras, despite its undoubted beauty. Distinguishing features include an adipose fin and conspicuously large scales. Males of the species are more brightly colored than females.
