These fish are hardy and great for beginners, and exceptional specimens can be bred by experts. Guppies are livebearers that breed and give birth right in the middle of the aquarium. In the 1960s and 70s the the World was swimming in guppy breeding clubs with beautiful fish winning first of show prizes. Then the reovirus, now just called the guppy virus. The breeding stocks from Thailand to Florida were wiped out. Now this live bearer has made a come back, with new varieties with ever larger tails and brighter colors coming from all parts of the globe. The endler, a related smaller cousin of the guppy, was discoved by collector John Endler in Venezuala in 1975 and is also enjoying popular success as a small live bearing aquarium species.
