He will get up to 18 inches. He is currently in my 125 gallon aquarium. I am in the process of turning my back porch into a greenhouse/terrarium and am going to be putting a 300 gallon aquarium out there along with a 250 gallon goldfish pond for my wife.
Yeah I would love to get an RTC.... I have a decent chunk of land to build a pond on it is just way to cold here for an outdoor pond.
