Often times large aggressive aquarium fish can become stressed from seeing nearby fish in other tanks or simply because they are seeing their own reflection on the sides and back panel of the aquarium. Some will try attacking the glass because of this issue so we have come up with a simple solution that is often used in the aquascaping world for aesthetic purposes.
We add the final touches to our Andinoacara Rivulatus "green terror" tank by installing some static cling Frost to the back panel of the aquarium. It is very simple to install and adds a nice background or works well as a side panel to eliminate reflections.
The frosting we are using is typically used to create privacy panels on windows or glass in the home. To install the static cling, you simply wet down the area you are applying it to and then use a squeegee or credit card to smooth it, while applying additional water to the back as needed. To get the measurements exact there is an easy to use grid pattern on the back to make it easy to cut to size before installing. It comes on a roll which was more than enough for our 75 gallon tank and was a relatively affordable option.
While the primary use of this product for us, was to make a nice background on our aquascape we will be adding a privacy panel to the side as well in the future to stop the line of sight into neighboring tanks. It is a simple alternative to painting the tank or using any other more permanent option. This static window cling can easily be removed at any time should we want to change things up. It is a tip we are glad we stole from the aquascaping pros.
