🍽️ Diet

Bronze Corys are omnivores and scavengers — but they shouldn’t rely solely on leftovers.
Feed a mix of:

• Sinking pellets or wafers (main diet)

• Frozen or live foods like bloodworms and brine shrimp

• Occasional blanched vegetables

🫧 Behavior & Compatibility

• Peaceful, social bottom-dwellers — must be kept in groups of at least 5–6 (they get shy and stressed alone)

• Great community fish; compatible with small, peaceful species (tetras, rasboras, guppies, etc.)

• Active during the day and love to “school” along the tank bottom

🐣 Breeding

• Easy to breed in captivity.

• Males chase females during spawning; eggs are usually laid on glass or plants.

• Remove adults after spawning to prevent them from eating the eggs.
