ok so weight Charlie and he is 30 grams. He gained weight real fast when I got him but it has slowed down. He loves when He gets outside time. I planted weeds from my yard in his enclosure. He tries to climb everything. He is too funny when my son goes to him in the morning he runs to his food...
I guess that means you don't know what a cuttle bone is.I didn't either. Is a flat white bone, you can get it anywhere that sells animal supplies or bird stuff. It's white. The torts will nibble when they need calcium. Just leave it in the enclosure.
I tagged Chris in this he knows a lot about Hermanns. If you post pictures he can get a better idea of what you are saying. Also what is his diet? What is his enclosure, heat, humidity, light.....
