how's it? Your English is fine. A thread is like stems of the same subject. I only have whites tree frogs, so I can't give advice on plants for the frogs u want. Although bromiliad sounds right. If u use the search on this site it will bring up like 500 threads of stuff related to your search. So type in "good plants for dart frog" and you'll get more info than u can read in a day. Good luck, and welcome to your new frog family!!!!
