These are young fish and haven't yet matured up.  The males get strikingly red.

Albino cherry barbs (Puntius titteya) are a stunning and peaceful addition to any community aquarium, displaying a soft pinkish-white body with a subtle golden sheen and striking red eyes. Their gentle nature and active yet non-aggressive behavior make them ideal tankmates for other peaceful fish species. These social fish thrive in groups of at least six, which helps them feel secure and encourages their natural schooling behavior. To keep them healthy and vibrant, provide a well-planted aquarium with open swimming areas and stable water parameters: a temperature range of 72-79°F (22-26°C), a pH of 6.0-7.5, and soft to moderately hard water (5-15 dGH). Albino cherry barbs are undemanding when it comes to diet, readily accepting high-quality flakes, pellets, and occasional live or frozen foods such as brine shrimp and bloodworms. Their playful yet peaceful demeanor makes them an excellent choice for community tanks, where they add both color and lively activity without disrupting more timid species. With their shimmering, delicate coloration and friendly nature, albino cherry barbs bring charm and harmony to any well-maintained freshwater aquarium.
