Thats a Japanese FB newt. They have a site in caudata.org just for telling the difference. Also, the CFB newts can't be kept with other kinds of newts, because many newts have their own toxins that they excrete, and tho' they're harmless more or less to us humans, diff. species of newt will get killed if kept in the same tank.
The CFB newt is one of the most common newts that can be found in pet shops in N.America, so if you do go with getting 2-3 for your 10 gallon, I can assure you, you'll be able to find a lot of info on these creatures. Right now, I have one in a 5.5 gallon tank, and he's such a great pet. So intelligent, and always comes towards you when you go look at him in the tank.
Main diff is that the CFB's have a smoother skin, and CFB's have a blunt, rounded tail tip while the tail of the JFB ends in a point.

Just incase ya don't know, newts aren't really good pets for kids because they'll want to handle the newts and pet them and such. Newts are great pets if you're happy with just observing them in their tank. I do handle mine when I do a WC tho' and after a while they get used to it, but I try to handle him as little as possible if I can help it.
Gimme a PM if you do decide to go the CFB newt way, I can prolly answer some of your questions.
