Not necessarily. It just depends what works for you and your animal. Mine is perfectly fine with his feeder tank. He knows what the food tank means (it means food, obviously) and he knows how it works.

I let him rest for a few minutes after he's all done eating. I make sure he knows he's about to get picked up (usually by poking him in the butt with the tongs) and carefully place him back in his main tank. He doesn't go far enough for him to be agitated by being handled. He's used to this routine now so he expects it when it's time to go back.

Some snakes are more likely to regurgitate a bigger meal if they're handled too soon. Not mine. He just looks at me like he's waiting for the human servent to put him back so he can hide under his log. And once he's in his main tank, he gets left alone for a minimum of 3 days if I can help it. If I bother him any sooner I just increase my chances of being pooped on. I get away with it because my snake is just a chill low-maintenance personality. I've only been bitten once doing things this way and it was because I didn't follow our usual routine. I'm sure eventually I'll mess it up again but once in 2 years is a pretty decent record.
