• Temperament: Peaceful, social, and active bottom-dweller; thrives in groups of 5 or more; excellent community fish

Diet & Nutrition

• Omnivorous: Yes
  • Accepts sinking pellets, wafers, and tablets designed for bottom feeders
  • Enjoys frozen or live foods like bloodworms, brine shrimp, and daphnia
  • Will scavenge leftover food but still requires regular, intentional feeding
  • Benefit from occasional vegetable matter like blanched zucchini or spinach

Appearance

• Pinkish-white to pale yellow body with red or pink eyes, a trait of albinism
• Shares the same shape and size as the regular Bronze Corydoras
• Fins are typically translucent with a slight yellow or pink hue

Distinctive Features

• Albino color morph of the Bronze Corydoras, resulting in lack of pigmentation and red eyes
• Constantly active at the bottom, often seen “sifting” substrate or swimming in bursts
• Has barbels used to detect food—fine, soft substrate (like sand) is essential to avoid injury
• Possesses a hardened pectoral spine that can become locked when threatened (take care during handling)
