  • Donatello, Petey and Syd

    Donatello (named after one of the Ninja Turtles) and Petey were acquired in Miami Beach, FL in 2005 from a family who was moving to Spain. They are 'Red Ear Slider' turtles who were born in captivity and we assume they are brothers. In 2007 Syd (named after Syd Barrett, first lead singer of Pink Floyd) was purchased at a Reptile Expo in Miami to join the others. Syd is a 'Yellow Belly Slider' and was very young when he was purchased. In 2008 the turtles made the long move from Miami to Colorado and were adopted by Boyd Lake Veterinary Center where they are happy and thriving. They live in a tank with goldfish and several varieties of tetras. Their tank mates need to be fast swimmers or they may become turtle lunch.
