gosh thanks for the nice compliments! Anubias is a good idea, or some other shade loving plant for that corner. The floating plant is wisteria, right now its roots are tangled in the top of the driftwood so it stays there. I used it to help start the tank, intending to take it out, but I kind of like it floating. I also have riccia floating... I prefer it floating to anchored, it makes these floating islands. I like how floating plants activate the surface of a tank.
