I know we can both argue until we’re blue in the face but I disagree on the backings on tanks. None of my fish tanks have it and I have enough smarts to know if my fish are stressed are not. I personally, think backings are ugly, cheap looking, and a thing of the 70’s. I will not use backings. The benefit (yes, I said benefit) to having a backing is it can enhance your fishes colors and cover wires. Therefore, if I were to use one it would just be a basic black so as not to cheapen the tank. As of now, I have found no reason to need one. All of my tanks (except one) back up to textured or colored walls so perhaps that sways my opinion.
