Any plants would work, depends on your lighting. what is the wattage on your bulb?. Also, tetras are known to be more difficult to breed than cichlids and livebearers. You have to have the perfect conditions. I'm guessing your tank will have quite low light, so you'll probably only be able to handle java fern and moss, or maybe some hornwort(sp?). And your tank will need to be fully cycled before your try any breeding. Keep water conditions pristine with lots of water changes and I hear that live food can induce breeding.
*EDIT* After doing a little research, here's what I found out. You need a temp of 75 and pH around neutral. And as with almost all fish, breeding is more likely if you let a pair form out of a school. (You could probably do 5-6 Buenos Aires tetras in there untill they are adults) I'm guessing its talking about java moss when it says you'll need a plant. Java moss is a low-light plant and will most likley work in your 10gal.
