Description: Hyphessobrycon roseus has a yellowish-rose colored body, the fins are red with no black markings. There is a prominent ovoid black spot behind the gill cover, measuring around half of the body depth. The dorsal and anal fins have white edgings.

It is quite easy to tell the sexes apart, the males are a little smaller and slender than females. The Yellow Phantom Tetra is an egg-scattering free spawner, exhibiting no parental care. Adult fish in good condition may spawn in a community tank, and even small numbers of fry may start to appear, but a separate tank is needed if you want to raise decent numbers of fry. The breeding tank should have dim lighting, and cover the base with some kind of mesh that can protect the eggs from the adults, or cover the substrate with a few clumps of fine-leaved aquatic plants (such as Java moss). The water should be soft, slightly acidic or neutral with a temperature of 26-28 °C, and the water should be 15-20 cm deep. Hyphessobrycon roseus can be bred in a small group or in pairs, but after spawning the aduls fish sould be removed from the tank because they may eat the eggs. The number of the eggs can vary betwwn 50 and 150. The eggs hatch in 24 hours and the larvae become free-swimming after another 4-5 days. The small fry can be fed with liquid foods or tiny live foods. The fry begin to color when they reach 1 cm in length.
