Ok thanks for that Byron, I will move it out when I can and post the pics. I have decided to take out the HC because it will not sit in JBL Manado and the fish keep pulling it up. I am going to put it in a Nano that we have. I am going to take out the tree and in its place try anf build up some sort of hill.
I will post pics as I go :O) Thanks again for your comments and ty to you too Barb :O)
There is no gap--to me. I like to be able to see through to the back of the tank at one point, as this helps a lot to create a sense of depth. However, one suggestion on this, you might want to switch to plain black for a background. Black construction paper works fine. I think the blue is distracting the eye a bit. Black would really make it disappear and create a perception of infinite space.
It looks really good. I would not fill in the back gap you have at all. It enhances your focal point where the rocks and bog wood is at. Plus I think it offers more swimming room for the fish. Heck in one of the pictures there was a fish swimming in the gap you are referring too. Great job!
Oh, what is the plant growing in between the rocks on the mound? That is an interesting concept
