Hey guys im a new member (just signed up like half an hour ago

) I was kinda hoping you guys could give me some advice

So i got my 1st snake 4 monts ago. He is a florida king snake. He has been great up until about 2 weeks ago. I put my hand in his tank to feed him and he just started hissing at me. he has been doing it nearly every time since. i go in slowly and im quite sure he knows i mean him no harm. He has taken a strike at me twice now. he is still very young (about 6-9 months...
