confuted: The floating plants are duckweed. I know it doesn't sound too appealing but I keep it under control by taking some out each week so it doesn't cover the surface. I also have a betta in there, and I'm planning to get 4 more white clouds this weekend. I would like some foreground plants, but unfortunately, the LFS doesn't sell many plants and the best I can do is anubias or microsword (but I read this needs high light).
Jessica: I'm planning to let my plants grow up and fill in the empty space, and if there are still empty spots I will add more plants.
ringram: Unfortunately, I only have normal aquarium gravel in there. I'm planning to put some plant tabs in the gravel. How much should I add? I'm afraid of adding too much because last time I added a few plant tabs, there was a algal bloom and I don't want that to happen again.
