Oops, sorry, I've had a lot going on lately and forgot to come back to this thread.

Yep, Squirt is a red eared slider, and as king said, they get quite large. Females get a good bit larger than males, and can grow up to a foot long. Squirt is too young to know whether he is a male or female right now, we'll be able to tell when he gets about 3-4 inches. Right now he's just 1.5 inches. He's about to be put into a 29 gallon tank, and at the end of this year, he'll be placed in his final tank, which will be 125 gallons.

He's such a sweet turtle too, he gets so excited during dinner time, it's funny to watch.
