Hello, I would really like some advise on how to fill in the middle of my tank. I broke up the crypts because I didn't like the way it looked completely surrounding the ship. Now I have a gap I need to fill. I would like to either carry the S. Repens from the sides or carpet it in....I just bought a bunch of S. Repens which I can use to fill the corners in but it's enough to get a great start on the middle as well. I am leaning towards carpet but thoughts please. Thanks!
