This will be my first turtle so I have just a couple questions.
1) Any tell-tale signs of what sex he/she is? I forgot to ask at the store and I'm not sure what I'm looking for.
2) Ever since he/she got home about a half hour ago he/she dived into the water and promptly sunk to the bottom. I expected a bit more grace, but then I know the turtles we see at the zoo aren't the same as the ones we get at pet stores. Still I'm concerned because he/she just had a little wading area in his cage at the pet store. I'm worried he/she might not know how to swim or how to get back on his island. Is it normal for a new turtle to crawl around at the bottom of the cage?
