Cobra guppies are exotic, brightly colored fish also known as fancy guppies. They have a unique pattern on their lower bodies and are available in blue, green, black, orange and yellow.
Cobra guppies require a 20-gallon tank that has a temperature range of 64 to 82 degrees. As adults, these fish can measure between 2 and 2.5 inches long. They have a peaceful temperament and are low maintenance. Male guppies are usually smaller than females, but they are brighter in color and have bigger tail fins. Cobra guppies have an omnivorous diet and thrive on flake food that is algae-based and meaty foods, such as freeze-dried bloodworms.
