Thanks for everyones input. I didn't realize how important the light would be. I had not had any trouble with any of the few plants I have so far, except for the fish eating them, but not all of them. I have a few I bought at petsmart for my 30g, when I first started. Then, I added about 6 bamboo plants and they grew pretty well. Also, I have some hornwart (sp?) floating at the top and that has double in size in a few weeks. I'll update what I decide to do. My 125g is still cycling right now, but it has most of my plants already.
