Ok so I got a new male black and white a week ago. At first he was pretty docile now as days go on he is becoming more and more aggressive. At first I could pet him and even hold him a little. Then he started hissing at me but could still pet him then today he is hissing and trying to bite. He is maybe 18" in length, he is in a 4x4x3 enclosure the temp on low side is 78 and high side 90 to 100 the humidity it 70 percent oh he is also spending a lot of time under the bedding which is cedar mulch and coconut husk mixed.
