There's a couple options....
1. You can pray for it.
2. Steroids.
3. Order it to.
4. Just kidding, just take good care of it, vary it's diet, make sure it's not overly stressed, make sure it's enclosure meets it's needs. Genetics do play a role in growth. Just try to be patient, and don't take steps 1-3 too seriously. Well especially step 2, DO NOT DO THAT![]()
