Thanks everyone. I've just heard that if you feed inside their cage they may become aggressive when reaching in to get them. Like I said, I'm new to this. I don't want to turn my (so far) quite pleasant and happy, docile snake into an aggressive one.
That's a myth. Feed him inside his tub/tank to prevent less stress and give yourself a better chance of him eating consistantly. I feed both live and F/T and both have their pros and cons.
