Ok, I know pretty much nothing about live aquarium plants, but I'd like to get some. Right now, I have only a 17 watt bulb(I was shocked when i checked it) for my tank, but if I got plants, I'd definitely get a 30 or 60 watt at least. I'd like some low maintenance grass-like plants to carpet the bottom of my tank. I don't want to have to do CO2 injections, or buy any kind of sand. I have standard fishtank gravel in my tank. I don't know if there is such a type of plant, but any help would be greatly appreciated. (especially comments w/ pics of the plants, or with links about them attatched) I have a couple questions: 1) How would this effect how I would vacuum out the tank? Would I be able to without damaging the plant's roots? 2) Would I have to trim the plants or pick off excess growth? (This may sound reeeeeally stupid and ignorant, but I'd kinda like something I can just plant, get a bigger light for, and it will just grow and look pretty) 3) I have a betta, a platy, a black skirt tetra, a neon tetra, a black mystery snail, and a male fiddler crab. Will any of these hurt the plants? Thanks so much guys! I've been asking a whole lot of questions, and you've all been really great about answering promptly. I love this website, and wish I'd found it a whole lot sooner.
