Nice tanl Sophos. You gonna plant a bit more, seems a bit sparse so far, and they do say fill it up with fast growers first, thats what I did anyway. I am in the process now of swopping the fast weeds for fast plants.
Also The gap in your background, Are you planning a plant to block the view to it? I can suggest a fiew giant Hygros. I got them in my cheapo collectiona dn they will grow until the hit the top, then cut the stem where it reaches the surface and it starts off filling out. Really fast grower.
I enjoyed reading through your journal as well. keep the good work up. Looking forward to seeing it with a few more plants in.
