I currently work at a childcare centre that happens to own a pet turtle. He is quiet big and they say he is about 10 years old. I'm aware that I'm the past he has not had the best care and has even had some shell break off, way back before I started. Recently I myself have brought two baby turtles and I have had them for a few months now! They are super happy and active. (I've had them for three months now) Anyway I'm buying a new calcium block for them again and I wondered if the turtle at work needs calcium blocks as I don't believe he has one. Should I buy one for him?? Does he need one at his age. His shell is hard and he often spends time outside when he can. He is very healthy now! Just so you all know. I also believe he needs a bigger tank but I'm not sure if the centre is willing to buy a big tank for him as it takes alot of maintenance and space. He is about 6" and he is in a 2 foot tank, what do you all think?? Should I talk to them about taking him to a sanctuary??
