You can't go wrong with Anubias and Java Fern. They are easy and fish love them. Also, the Anubias blooms flowers sometimes. It is a very rewarding plant to have. When I first started with live plants, I checked
www.plantgeek.net
It is a very helpful website. They have scientific names, common names, pictures, care requirements, etc. Also, there are different ways to look for the plants that would fit your needs; by light requirements, placement in the tank, or just by general care requirements, such as very easy, easy, moderate, difficult, and very difficult. It is a great website.
