I am really glad you enjoyed the pics, I will have some youtube videos coming in time, of him hunting, eating, swiming, you name it and I will be getting it on tape this summer since I want to remember how small he was because they get BIG:
That is huge and they need like a 75 gallon tank to accommdate them at that size, so in time we'll be getting one or making one out of plexiglass, who knows? Ever heard of
Craigs List? Its got all kinds of stuff listed, from cheap used items to free items and I hope to find a good deal there locally, check it out it's even got housing ads! LOL!
Then I also check the local
freecycle.org group which you can probably find one in your area too, they have only free items that have to be in good enough shape to reuse and it saves the landfills from filling up with good stuff that still has life left to it. As for his sleeping habits he does sleep underwater, they can hold their breath for a few hours believe it or not, the first time I saw it I was sure he was dead, but he was just resting...Hehehehe!
Here is a pic of the tank with the 'Basking platform' he has:
You can see how small he is compared to his tank, but I know that won't last long, they can grow up to like 5 inches in a matter of months at least they do from the start of their lives, I think they then slow down growthwise, but even so hubby doesn't think we're getting a bigger tank, but I know we're going to have to when the time comes at the fall of this year, which I think is when he's going to become a semi-adult.
If you or anyone else has any questions fire away and I will do my best to answer them.

I have learned so much about turtle care over the past week and a half that I have been absorbing info from
Austin's Turtle Page website which also hosts this incredible forum of people all devoted to our reptilian friends called
http://www.turtleforum.com/ both have a wealth of info on all kinds of species of turtles and TONS of photographs, so you can appreciate the beauty of the animals.
