Assorted GMO/Glo Danios are genetically modified Zebra Danios (Danio rerio) bred to possess vibrant, fluorescent colors (like green, yellow, blue, red, purple) from jellyfish or coral genes, making them popular, hardy aquarium fish that glow under blacklights. These aren't dyed; the color is permanent and inherited, offering easy-care options for beginner aquarists looking for colorful schooling fish.
