This is our 5 year old Fantial Goldie, named Curious George by our then 5 year old son. We were uneducated and he was a baby so he came home in a 2 gallon with no filter! He was soon moved to a 10 gallon filtered tank, where he got a 'friend' (another fantial). George did not get along well, had murderous intentions and poor Chuggington did not make it. George is a loner but well loved and he didn't take long to get big enough for his current home, a 20 gallon long.
