I have never heard a hiss in person this loud from a snake. They are very pissy and I think I will actually not bother them until feeding day and maybe awhile after that lol. The Rosey boas we got with them didn't even act stressed like they had been in a box for a day.
There faces and the way they move kind of remind me of a bird of prey and I am actually slightly intimidated by them even though they say they close mouth bite. They vibrate there tail so fast its like a cell phone on vibrate. They were a "suprize" from the guy I bought 8 rosies from lol and I wasn't planning on getting free snakes that grow to 4-5 ft, oh well guess I will look for some more 20 gal longs lol.
