I'm new to aquarium plants - I currently have a few anubias attached to driftwood and I'm using liquid fertilizer. I am preparing to order some easy, low-tech tissue culture plants to add to the tank. I like the look of moss on driftwood - the forest look - but I don't want a plant that will take off and invade my entire tank. I'm hoping for suggestions for something that will give me that moss-covered wood look without the aggressive growth of the mosses I've read about (java, christmas, etc). I have a 46 gallon bow front with 2 WavePoint Sun Wave High Output T5 12,000K Daylight Lamp lights. I have black diamond blasting media for substrate.
