The Red Dragon Dumbo Ear Guppy is a striking freshwater fish known for its vibrant red and metallic blue coloration, resembling the mythical dragon. It features large, flowing pectoral fins (nicknamed "Dumbo ears") that give it an elegant, fluttering swimming style. Males typically showcase more intense colors, while females have a subtler hue. Guppies are one of the most popular fish in the aquarium hobby. They are gorgeous fish that come in so many different strains and colors. Like other livebearers, they need a good amount of calcium in their system, so they do best in harder water.
