(terrapin) growing fast

My female diamondback terrapin, Bigmam eats really well these days.

Now her weight is almost the same as Kujan.

 From the pictures, I can see her gray lining.

As time goes by, the lining will harden and become the outer part of the carapace and plastron.

I like to call the lining the 'growth line'

Her 'growth line' is so wide.

It's about 5mm long.
I believe she can grow fast and big.
Bigger female terrapins can lay more eggs than a small one.

For her health, I feed her a variety of food
Arowana by Tetra, Saki-Hikari turtle by Hikari, Aquatic turtle by Exo-terra
and dried anchovies.
