Guppies are one of the most popular fish for aquarists, and there is a wide variety of guppy types to choose from. In general, the two main divisions among guppies are based on their coloration: wild-type and fancy. Wild-type guppies have natural drab colors that blend in with their environment while fancy guppies have bright vibrant colors like red, orange, blue or yellow that make them stand out in an aquarium. However, depending on how you classify them there can be anywhere between 20 and 600 different types of guppies! Some aquarists even specialize in breeding specific varieties such as Albino Mosaic Guppy or Endler’s Livebearer Fish. No matter what type you choose though they all share some common characteristics; they tend to be peaceful community fish, they prefer warmer water temperatures (between 75F-85F), and they usually reach around 2 inches in length when fully grown. All these factors combined make the humble Guppy a great choice for any beginner aquarist looking to add some life to their tank!
