[Woodendog]

Have six Multis in a 33 long, 12 tall . Planning an easy planter and root tabs due to the full sand substrate. use of plants is  for visual and sight break. this is first plants in any tank for me> best plant to start with that I can order from coop?

Some really good beginner plants are:

-Any floating plants

-Java Fern

-Anubius

-Crypts

-Valisenaria

-Amazon Swords

-You wont need root tabs for the anubius or java ferns, they are water colum feeders.

I grow Cryptocoryne wedtii, Vallisneria, dwarf hairgrass, and dwarf aquarium lily well without any fancy substrate (I use pool filter sand) and without any fertilizer (I've had all my plants for about a month and a half). But since I don't have any fertilizer/root tabs, my Amazon sword doesn't grow well, and the Vallisneria doesn't carpet very fast either. On the other hand, my crypts and lily bulb are doing extremely well. I even planted Java fern in my sand and it is the biggest plant in the tank already (it started as a mystery leaflet amongst floating plants I bought from my LFS). So I would recommend pretty much all of the plants that @James Black just mentioned, plus dwarf aquarium lily.
