beeps have been known to hit the proverbial "wall" when it comes to eating and weight gain. once the snake reaches a certain size (typically ~1000g) it's a known phenomenon for beeps to go off feed. my male hit his wall at ~700g over a year or so ago, and it's been a slow and steady climb to his current 900g+ weight.
this is typical and nothing too concerning. offer every 2 weeks from now on until you start getting a consistant acceptance of food.
I have recently took him to the vet. My vet did not seem to find anything wrong, and that said that he is at a healthy weight. He said this happens sometimes and that he will eat when he is ready. He didn't seem concerned about it at all..so it probably is just me worrying. Which I figured.. my boy is part of the family so I do worry about him a lot XD. Thank you for the replies.
