I have purchased a 90 gallon aquaium and wanted to make it a planted tank. I am going for a dirted tank with tahatian moon sand over top. I also have a large peice of driftwood that I will cut and prop up in the corner so it's sort of like a cave. But I need some beginner plants! I plan on putting java ferns on the driftwood but other than that I'm lost. I want some sort of grass type of thing to put around the driftwood. I also need a good taller plant to put in the back. For other decoration shoud I use small peices of driftwood or get some sort if river rock? Any ideas/suggesions would help! Thanks!
