Sand Boa

I got a sand boa in June, he barely filled up my palm when I got him. He went on a feeding strike for a couple weeks but he has been eating a pinkie every week. He refuses to eat more often than that. Anyway my question is, how big do you think a 7 month old sand boa should be because he is just bigger than a pencil. I'm just concerned because my other snakes are growing like crazy but he doesn't seem to be gaining any girth or length for that matter.


Thanks!

Don't worry about it, if it's a male then it probably won't exceed 20 inches in its entire lifetime. The females get a bit larger, but if it's a male then you really shouldn't expect it to grow like other snakes.
