Hello, I have a female corn snake who is about a year old. I've had her for 7 months, and shee has never exhibited any signs of aggression until now. She has refused to eat this week and is striking at anything that moves in her tank. She also seems to have gotten very skinny all of the sudden. I have been feeding her 2 f/t fuzzies a week. She has been defecating regularly, and all the temps. + humidity are fine. I am keeping her in a 20 gallon long aquarium on fir bark with an undertank heat pad. Please help me, I have no idea what is going on couldn't find anything that gives help on my situation.
