I had bought a pair a year ago, but the female {pooh} ended up growing up to 3.75 inches. She then started nipping at spidey, so i gave her up to a pet store after watching in horror how she grabbed spideys leg and dragged him in the water.
He was a little stunned and wouldnt go in the water for a week. this occurred about 2 months ago. After that week of closely watching him..he went back to his social self. Hes very warm and doesnt seem to be scared of me, he slides when other people approach him though. He does these little cute things which reflect his trust in me. He was perfectly fine upto 2 weeks ago.
He has suddenly gone into a heavy sleep. He sleeps in the water or on the basking spot with every appendage extended completely out of his shell . Ususally when he was sleeping I could wake him up in a snap. Now it takes several minutes....even if im holding him. He does eat, and is still his playful self. I really miss him swimming into my hand voluntarily. I have done some research and the only reason that kept coming up is turpor. This is my first res can someone please offer their valuable advice?
, the only thing you forgot was the age and size of the turtle.
