Don't keep goldfish or red parrots, you'll never see them, do post pictures!
Beauty is in the eyes of the beholder!M3AN ONE its your tank buddy do as you wish!
But if it doesn't look good! I'll be the 1st to talk ish! Lol we gonna roast that tank! Jk! But honestly orange will look good, it all depends on his decor. I'd say some dark and light brown decor, rocks , dw, and even black goes very well with orange. With a tan or dark substrate it'll look pretty interesting. I thinkThat's what those people with blue gravel say lol
The background of my 180 is a piece of 1/4 inch plywood that I painted black. I can remove it and repainted it whenever I want. Might try blue soon. Easier than redoing the glass.
I used black duct tape at the left and right side. Ran it straight and it looks fine.How did you attach it to the tank? I might try this for my acrylic tank.
