Thank you! Yeah, any one in the bag will probably be fine. If you want to be extra safe, go smaller for the next few feedings and then grab any one.
I think you will be surprised how fast your guy will grow. When young, a lot of that food goes towards growth!
I probably mentioned, and sorry if I did, but it's a good idea to get a scale, even a cheap kitchen one on amazon that does grams. You will want to monitor his growth in weight and also be confident about when it's okay to move up in prey size, etc.
Good luck and keep up the good work!
