My WC T. Elegans Vagrans, who I have had for about 1.5 years, has just reached over 12". I think he was about 7" long when he came to live with us. Does that rate of growth seem okay for a male?

When do garters reach full maturity? Do you all think it is likely that he can reach the 2' mark? I had read that t. Elegans could reach up to 3' in length, but then read another source on sexing that said that the males tend to be MUCH smaller than the females....
