I'm not a breeder; just a small reptile hobbyist.
I have a question on my late '08 Spider male. He's gotten so grumpy!
His temperatures are correct and he's eating wonderfully as usual. But he's been peaking his head out his hide, constantly in an s-position which looks aggressive. If I come close to his tank, he keeps his s-position and looks as if he's trying to strike! He's actually only striked at the glass once and has never bitten me. If I go to pick him up, he doesn't actually try to bite, but just keep that position.
He's been doing this since the weather changed and only at night.
Any ideas?
