This is HOMMER, He is our biggest male aldabra tortoise. He was 640+ pounds when we purchased him from a zoo many years ago, we guess at his current weight. He is a great breeder and ultra strong. His temperment is gentle and he likes to hang around the ladies! I had to add a third layer of 2x10x10 boards because he climbed over and destroyed all of the areca palms. Well worth it, he is a blessing in many ways and we are so fortunate that he is at our breeding program. Yes, our fertility did improve once he arrived.
