My Russian tortoise will be one year old next month, and I can’t find any good growth charts. I’m nervous about his size and whether or not he is progressing or if I should be feeding him more, etc. His length is currently about 2.25” and width is 2.75” and he’s weighing in at 55 grams pre-soak. I’m not sure if this is normal or if he is underweight. He’s still a pretty small guy but seems to be growing steadily since I got him. I just wanted to check!
