yeah, mosses are great, terrestrial and aquatic. I really like my dwarf sag, because it grows well, took root quickly, and the otos like to lay on it, which is pretty cute. I love the look of glosso in pictures, except for my pictures... lol. it's such a pain. I also have a red leaved bulb plant that I like a lot, don't know what it is, but it's the same color as the cherry barbs, and they seem to like to congregate around it. madagascar lace is also very cool, but from what I read, a pain once it flowers... people reccomend taking it out, and storing it in a cool place for several weeks and then replanting it.. guess it needs a dormant period.
