Picked up a new baby, and she's "tiny". Possibly problems?

Both girls are doing amazing! I've decided to call her Ruby, as she's as grumpy as the "Ruby" from Supernatural. Anyways, she's eating steadily, First 2 weeks, she got 1x fuzzy 2x a week, now she's on 1x hopper every 3-4 days. She's gaining weight like crazy, she's sassy, active, she's not dull anymore. She's gone from 54g to 92g. I couldn't be happier.

Pixie, her "sibling", has gone from 46g to 78g, she's getting spunkier, eating without a problem, active, shiney, all in all, I'm stoked.

The original owner/breeder finally got ahold of me. Their hatch date was Sept 24th/25th. He doesn't remember the exact day. So they're 5, Five!, months old, and not even a full 100g. They both should be at least 150-200 by now. I also found out that they are twins, same egg, which I think is amazing, I didn't know that was possible.

If anyone would like, I can post an updated picture of Ruby, she looks so so much better.
