Hey guys, I'm getting my first Ball next week. I have his home setup and it's running steady. He is a 2011 and weights 68 grams right now. I need to go ahead and order some rats for him but I'm not sure what size. I am in the air about where I am going to get them from right now and just wondering what the weight of his pray needs to be AND about how long before these guys move up in pray size? I don't want to order too many of a size then have left overs too small for him and need to get bigger ones. I just really want to do the right.
