I tried a static vinyl Fish Tank Background Sticker and couldn’t believe the difference in the quality of my aquarium’s decor. Talk about a transformation.

What Are Fish Tank Background Stickers?
Fish tank background stickers are self-adhesive vinyl designs that attach to the outside of your aquarium glass. Unlike 3D backgrounds or painted options, they’re affordable, easy to apply, removable, and available in a huge variety of designs—from realistic underwater landscapes to abstract or seasonal themes.
How Much Do Fish Tank Background Stickers Cost?
Good question: in comparison to buying a large pirate ship (approx $50) silk plants (x2 $25 each) fake log ($29.99) so far $130 a couple of plastic plants $50 = $180. A 2,5 metre wide aquarium background is $139,99 less $10 with coupon code $129.99 with free shipping, For the extra $60 you would get approx 8 real plants and an awesome background sticker.

Types of Fish Tank Background Stickers
1. Vinyl Cling (Static) Fish Tank Background Poster
These are static cling backgrounds that require water and a bit of soap, or vinegar and water solution to hold them in place temporarily and then be able to easily move them around. For large fish tank wallpapers, as they are sometimes called, ours are cut down into easily to install pieces, numbered to make it easy for you during installation.
2. Self-Adhesive Vinyl
More durable, weather-resistant and a little more difficult to install. Available in matte or glossy finishes. These vinyl backgrounds have a glue applied, so once you touch the glass with the glue backing, it’s sticking, making it more difficult to et them on without them bunching up, and getting air bubbles. Generally come in 1 piece.
3. Printable & Custom Backgrounds
Downloadable files you can print at home or have professionally printed for exact sizing.
4. Pre-Printed Posters
Sold by pet shops or online retailers. Rolled paper or plastic designs to tape to the tank. What makes these hard to work with is they don’t cling to the glass of your fish tank, so that makes the image more difficult to see. After time, they move further away from the glass, gather dust, until they fall down. The other problem is they need to be stuck to your aquarium with sticky tape and we all know how long sticky tape sticks to glass for. N

Sizes and Fit Guide
From 5-gallon to 125-gallon tanks, background stickers come in multiple dimensions. Custom-cut options are best for tanks with unusual dimensions. We recommend with our static vinyl fish tank background stickers, that you order the size a little smaller than your tank size, so you won’t need to trim your background.
Alternatively, you can order a little larger and trim over hang with a Stanely knife, box cutter or a crafting blade.
We have a final option and that is ordering to your exact aquarium size, of which case, just reach out to us with a quote form.

Clean the exterior glass thoroughly with alcohol-based cleaner.
Spray the glass with a light mist of water and soap or water and vinegar (optional for repositioning).
