Man, mines been doing that for awhile now. He's been putting about a month to a month and a half between feedings starting around early April. I offer weekly, but he won't take it until he's ready. Relax, everything's fine most likely.........males are notorious for this :wink:
My advice is to just wait until next week's feeding time and try again. If he doesn't eat it wait again.
Always assuming you have the temp of the body right if you're feeding f/t.......that can be tricky but you've been successfull so far which could mean he's just decided to slow down for awhile. As long as he's not getting skinny or showing signs of malnutrition I wouldn't worry. He'll eat when he's hungry.
Doesn't it just bug ya tho? :?
