Hi
I do think 18 months is a touch young for him to be sexually mature, so I wouldn't go back to that particular guy in the reptile store.. Have his temperatures changed at all? I wonder if it's got too hot in there for him for some reason...?
You are in the right place to ask questions; although I am hardly one myself, there are many experts on this site who will be able to help you.
Right..
When you say he "acts as though" he might bite you, do you mean in his movements, or has he actually struck at you?
It's not impossible that breeding season could make him suddenly more aggressive (if he is old enough), although I think it's more common just for them to be VERY active and wanting to 'check everything out' - does this sound anything like his current behaviour?
I honestly think from what you have posted so far, that he may be older than you were lead to believe and it is nothing more than the time of year causing this strange behaviour. He is showing all the signs definitely - active during the daytime and not eating for example.
To answer your final question, it could last anywhere from a few weeks to a few months.
My advice would be to try not to over-worry. Keep a close watch on his health and the conditions in his vivarium (expecially temperature). Offer food every 2-3 weeks and
expect him to refuse it, but when he goes back to normal you can return to his usual feeding regime.
I hope you can figure this out soon
