It's a bit late now, but you should quarantine new turtles for at least 90 days. They're very good at hiding illness.
Also, make sure your tank is big enough to accommodate two turtles.
Keep an eye out for aggression. The established turtle may become very territorial, and fight with the new one. This can result in serious injuries. There is a very good chance at some point you will have to buy two complete setups and separate them.
Finally, as take-one said, the new one will take a while to calm down and start eating.
If the first one was eating, and now he isn't, that's not a good sign. It could be that the new one has transferred illness to the first one.
