I bought him about a month ago and he is a live eater. I am trying to switch him but he's being stubborn about taking F/T. He hasn't eaten since I brought him home so its been just over a month. I may buy a live weaned or hopper rat to get him going and then try a F/T right after. I just said he would be 100 grams more on the light side, he should be pretty close to 900-1000 realistically. I wasn't concerned until I got the 3500 gram girl and was looking at them in comparison. Thanks for the replies.
