Wow, what a lucky find for free! Looks like he loves it, too, and it has so much room for him to grow into!!
As long as you keep feeding him well and keep him healthy, he'll keep growing. I've heard they grow well into their second year.
That's reassuring for me as well, because my Eri is a smaller dragon, too.
Tonja said her Emmett is 17" at five months, whereas Eri reached 17" about January this year and has stayed there. He's one year and seven months old next Sunday.
Some dragons are small, some are big, and some have sporadic growth spurts.
I've taken pics to track his growth, always posing him with the same object to really notice the difference. I look back at them every once in a while because seeing him every day it is hard to notice how much he changes. If I could do it again, I'd take these photos more often.
About a week after I got him, apx Nov 20, 2012, apx 5 weeks old. Just under 4".
March 22, 2013, aprox 5mo, 9 1/4"
May 14, 2014, aprox 1y 7mo, 17"
(Sorry if you don't want these pics here, I can remove them)
As for the name, I totally understand, lol. As you get to know each other, I'm sure the right name will come to mind.
Glad to hear he's got a good appetite (especially for worms)!
Can't wait to see more pictures of 'Beardie' and watch him grow up!!
