This species—while lacking some of the more intense coloration of some other tetras—is, nevertheless, every bit as beautiful when in good condition and kept in a shoal. In such circumstances, the bold gold and black lines that run from the tip of the snout through the eye and on to the base of the tail stand out to great effect. Ulrey’s Tetra is sometimes confused with Hyphessobrycon heterorhabdus (Flag Tetra) from the southern tributaries of the central Amazon region, which has a reddish line, rather than a golden one, above the black body stripe.
