I measured my Indian Star today and she hit 3 inches, I'm not exactly sure how old she is but I believe her to be close to a year old, I have had her since April,she has grown 1 1/4 inch since then. Don't know if this is a good growth rate or not, She is different in the since of keeping her enclosure neat and clean, I'm used to tortoises trampling and destroying everything in sight but not her, she can get a little messy with the mazuri though.
