Wow 700 grams in one year that's amazing. S/he is so beautiful , what do you feed him/her? The shell looks really smooth too, do you have her in a closed chamber?
I offer a mix of these depending on what I have: grass, romaine lettuce, spring mix, kale, carrots, greens, hibiscus and spinach very sparingly. I offer tomatoes and strawberries in small quantities as a treat a couple times a month. I also give soaked Mazuri about twice a week. I sprinkle his food with Rep-cal calcium a few times a week as well. Lighting and humidity is also very important for growth.
