I just recently bought an adult Pastel Sugar, he loves to hiss and sometimes strike at me. I've learned to open his tub, take out his hide and let him come out on his own so he doesn't feel threatened by me grabbing him. He likes to explore so it doesn't usually take him long. Also I bumped up the size of his meals, I think it was a combo of stress from the new move and the person before me was only feeding him mice. He's starting to come around now.
