Background Choices

Painting the back with acrylic latex paint is popular(Blue or Black is the best IMO).
Comes off relatively easy if you want to remove it.

Cork backgrounds on the inside and attaching plants is also very nice(gives another surface to plant on and is easy to plant with Anubias, java fern, moss etc)

Some add terrestrial plants in the background.

Some use paper, cloth etc, these don't look good IMO.
Paint looks much better and is easier in the long term.

Some use Styrofoam and mould/paint/silicone it.
Some used moulds of rocks, wood etc that they like and make a silicone rubber moulds to form their shape, designs etc.

Some use flat rock silicomed, glued together, some use rock with sand, gravel glued to it etc.

There are other methods also.

I like plain color backgrounds, IMO. I think they look more classy
than Greek ruins, rock crystal, saltwater reef pictures, etc.

I have seen well done tanks in many colors: yellow, red, blue, white,
black. Yellow was especially beautiful in an ADA aquascape titled
"Little *****" with cardinals and altums. The deep yellow color reminded
me of the tannic acid stained waters of the Rio *****.

Currently, my 55g has a sky blue background, and I think I may go with
white on my 20g long. I'm not too crazy about black. I feel that a black
background is kind of like omitting the effect of the background on the
aquascape. Yes, it makes the plants stand out better but it doesn't
really evoke anything...

Background color will definitely be a future "weekly topic." I'll post
some examples at that time.
