Back to Nature Orinoco 120cm x 47cm. A perfectly natural looking three-dimensional landscape, that creates a stunning visual experience in your aquarium or terrarium. All Back to Nature backgrounds are crafted by hand to perfection. Orinoco is a flatter background which perfectly fits into modern aquarium furniture which is not as deep. In spite of these backgrounds' relative flatness and their reduced need for space in the aquarium, there is still enough space in one corner for both the filter and the heater. This background is supplied in two sections, simplifying installation.
