just for a quick rundown on him

ive had him for over a year and have been feeding him live started on mice moved to rats at the of may and hes been eating fine but recently his feeding has been all wacked 5 weeks ago he downed a meduim rat just fine and then the next week he didnt eat. no big deal . i fbring the rat out 3 days later nothing doing. continues for aound 2 weeks. he never touched the rat. i finally gut pissed off and returned the rat cause i was spending more time taking care of the rat than Monty.

i waited a couple of dayz (till yesterday) and bought a smaller end rat (not juvie but a small medium) and last night he wouldnt touch it. its in the cage right now running circles around him and he wont even look at it. hes had rough feedings before but im getting worried.

thats the regular part about all this. my MAIN CONCERN however is that when ever i get near the tank now he immediatly goes psycho hunting mode and snaps at me!!. i mean like ill walk pass the cage and he'll lunge at the glass!

so i got below level of the tank (its on an aquarium stand) and i "snuck up on him" and i noticed a bit of scale rot on the underside of his head (sort of like a few stringy looking things and a few brown spots) and im wondering if its a combination of all these things that throwing him off so bad


a little help here please
