Ive got a male yeman, had him for almost a week, everytime i go near his tank he fires up and hisses and tried to bite, is he always going to be like this, or is there a way of taming him a little? I no there a look no handle pet, but im thinking he'll be a nightmare like he is if he ever needs the vets. Ive tried offering him waxys and bugs but he just hisses and lunges. Thankyou
