I took a close look at Jamal today, and it looks as if the outer edges of his shell are chipping, and they are a light color. The middle of his shell, where the scutes meet is also a bit rigid in one or two areas. After doing a little bit of searching and reading, I've come to the conclusion that he is growing!
He's very active, swims a lot, floats around the top of the water, eats well... doesn't really bask under his lamp too much, I think he's still getting used to his playpen.
Other than that, he's one happy, and seemingly healthy little dude!
That's all, just thought some of you might be interested.

You can see the different color of the edge of his shell pretty good in this one...
