My male rosy, Swagger, has become very aggressive. I purchased him back in october at the orlando repticon and he was fine for about a month. Would let me handle him with no problem. But after that first month he would bite and strike at me from behind the glass of his tank. I have never fed him in his tank but in a separate 5 gallon tank, and his aggression is much worse in this tank. I've been told that it is a feeding response, it very well could be. But I work in the medical field and can't go into work with little bites on my hands. Is this normal for young rosys, or do I just have a particularly nippy snake. A little info about his tank. Right now, hes housed in a 20 long tank, with shredded aspen sub straight, warm side of the tank is right at 90 degrees, the cool side is in the high 70s to low 80s, night time temps are mid 80s on the warm side. He has several hides and lots of plants spread throughout the tank.
