Hi there,
I've had my red eared sliders for the past 15 years (They're at least 15 years old, I'm not sure how old they were when i got them - they were small)....
They've always been very friendly with people and eachother... They've had the same habitat and feeding schedule for years... Suddenly they've become aggressive, and I cannot put my finger on what's causing it. I went to check on them 2 days ago, and one turtle was clamped down on the others neck, and today I went down and one turtle was chasing the other with his mouth open ready to attack... The aggression is with both turtles, not just one.
Any suggestions???
