Poeple often ask for recommendations for good starter plants. I've found an article that lists some good ones:

Of the ones they mention, I have Cryptocoryne wendtii , Dwarf Sagittaria (Sagittaria subulata), and Java Fern (Microsorium pteropus). All are doing well, except that the Java Fern grows so slowly that many of the leaves are covered in brown algae. The other ones grow fast enough that I can cut off the algae-covered leaves and still have some plant left!
