Its weird how they both done it but they are from the same batch , they are still growing but way slower than other peoples have , my irwini was just starting to hand feed and grow quicker and I lost him at 10"
What are u gonna do with yours when it gets to 40 pounds? And it will get that big UNLESS you stunt it! (I sound like I am hating but i am not, If I come across that way I apologize...)
Best of luck dan!
