Haha, this is a herp discussion group! You don't need to ask for an argument to get one, you literally often just need to say hello
In this case someone immediately jumped on with a blatant lie/exaggeration (a common theme in herp groups) followed by inevitably being called out
Just roll with it
Don't let it worry you
You'll also take some time to learn how to identify who is worth listening to and who is a loud-mouthed newbie with nothing worth saying.
Captive Stimmies usually end up something around 90-100cm. Really big ones can get over 1.2m after several years, but many will never reach 80cm. Anything from 50-75cm or so at 1 year of age is fairly reasonable (a 75cm one will be much much heavier than a 50cm one at that age). Especially for newer keepers, the usual feeding regimes shouldn't get them to the upper end of that range by a year, and something around 60cm and in the ball park of around 80-100 grams is pretty good, but if it looks healthy you're probably doing well. How quickly they grow and how large they eventually end up largely depends on how much you feed them.
