hello dennisb. Im glad you are taking interest in a planted tank. About purchasing plants, I think you should definetly do a significant amount of research about which plants are best for your tank before purchasing them at the store or online. I spent countless amount of money cause I just jumped right into it without research and end up having misreable looking plants barely clinging to life and eventually wasting away cause I didnt read about them (some plants love really bright light and some dont, etc). I also warn you about purchasing plants on ebay which I did. I purchased away thinking Im getting a good deal due to their item titles (i.e java fern 50 plus leaves) when in fact your paying more due to added shipping per each item plus when you get your plants it looks like they shrunk it compared to the pictures online. buying in bulk or locally or from your lfs is better. heres a site where I bought some plants www.azgardens.com. there are tons of sites out there. I also recommend purchasing this book..well worth it if your beginner or even advance - encyclopedia of aquarium plants by peter hiscock. Have fun plant hunting
