He's a really silly bugger, he'll be doing it to me whilst looking out of the side of his tank on feed night without me even facing him. It's the same thing every time, he does the push ups which is obviously completely terrifying, and then once he has decided the push up tactic isn't working, he grunts like a pig and makes a dash for the nearest hide. My others don't do the threat displays at all. They are a very nervous species by nature, so they are all what I would call 'jumpy', but not aggressive like this fella.
He has bitten me, but it doesn't hurt, much to his dismay!
The camera is a Kodac Easyshare, it's not the best, but it does what I need it to do.
