This will be the last update with the background. The fish and rays are getting too big for it and I want to redo the filtration as well and it is really hard since the tank is not drilled and its hard to run pvc around the background. After vacation I will take it out and paint the back wall, bottom and half of both sides black. The overflow will be painted black and I will have some sand in there.
Question? Is it bad to spray paint the INSIDE of the tank. I cant lift this to paint it and I cant get behind it either without moving it. Is it bad to spray paint in the tank? What is the best method there?
