Wow...I just read this whole thread because I just started with plants myself. I did a whole lot of online research and got pretty good info. I now have a pretty heavily planted 5 gallon tank and can maybe offer a few suggestions on plants. My tank is a Fluval Spec V and it came with an over-the-tank led light fixture. Not being sure what the level of light really is, I chose low light plants. They all seem to be doing good. Here's what I have. One nice Java Fern, Anacharis, 1 Anubias Nana and 2 Anubias Nana Petite, Jungle Val (which is kind of grass like with slender leaves that I hear can get very tall...you might want to look into it for height), Bacopa Carolinaian (which is also taller), Java Moss, Cryptocoryne Parva (a short variety of crypt), 1 large, 1 medium and 3 tiny Marimo Balls. Google the plants for more info or you can ask me and I'll tell you the bit I know. I get my plants from ebay and Amazon.com since I don't have a LFS and the closest PetSmart is about 40 miles. I need to get root tabs for my crypts, but so far I have not used any fertilizer. I do have some liquid fertilized that I am going to start using this week. Hope you and I both have good luck with the plants! Mine aren't amazing yet and they might never be, but so far I have kept all of them alive and looking pretty good for a beginner. I got tired of the fake plants really quick and heard it was much better for the fish to have real plants. Try to remove any dying or dropped leaves regularly and once the plants get going they might need a trim from time to time. My Anacharis (not sure I'm spelling that right) has gotten trimmed a lot already because it grows really fast. The tank is kinda short and I don't want them to get very long and shade the rest of the tank. I've cut them back and added it to other tanks. Again, good luck!
