Any tricks to get stubborn males back on food?

Fasting is super common in ball pythons. I wouldn't let it worry you too much. 200g for a snake that size isn't really that bad. It would be nice to get a meal or two in him though! My pastel female was off feed for over 6 months. What broke her fast was me bringing home a trio of ASFs to start a colony. She has been eating every week since I brought them home.

There are tons and tons of tricks for getting ball pythons to eat, but nothing is guaranteed to work. He will eat when he is ready. You could try moving him back to his smaller tub? If that is enough to get him to eat for at least a few weeks it would be worth it.

Hi everyone, thanks for the replies. I have some more info:

-He ate no problem for two meals in October, then fasted.
-He was introduced to a female and bred multiple times with her.
-Last lockup was in December.
-That female is not housed in the same room with him anymore, the only other bp in the room is a 9month old female.
-I thaw my rats in water, then run under hot water then blow dry. I will wiggle it with the tongs or dangle it by the tail (his favorite offering) but at the last second, he just turns away. I will try this until he crawls away from the rat, then I leave it in overnight.
-The last meal he ate was in January. It was a small f/t rat.
-I usually feed the female first, but I will sometimes offer him first.
-I scent the room 5 minutes prior to offering.
-I've tried him on aspen and paper towel. It doesn't seem to make a difference.

I'm just started to worry about him because he's usually pretty chunky. He's a 2009 between 3'10" and 3'11".

Thanks for all the help everyone.

just another thought... you might try thawing in the fridge and leaving in the room for 30min to 1 hour to warm up to room temps and pre scent. Then carry on as regular. i find rats smell less after the hot water bath... (maybe leave the water out in the room?) anyway a real dense pong of rat in the air may help... Just a thought.
