poluu Fish Tank Background,40x200cm Static Cling Aquarium background Decor Black Backdrop Sticker Self Adhesive Underwater World Wallpaper for Fish Tank Decoration No Glue Residue Cut to Fit

• Large 40x200cm Size Fits Most Tanks & Fully Trimmable: This aquarium background measures 40cm high by 200cm long, long enough for standard 20-gallon, 40-gallon, and 55-gallon tanks. Use scissors to cut it down to fit smaller bowls, nano tanks, or oddly shaped aquariums. One roll covers multiple small tanks or one large setup – a versatile fish tank decoration for any home or office display
• Static Cling – No Adhesive, No Sticky Residue: Unlike traditional glued wallpaper, this black backdrop uses static adhesion to grip glass instantly. Apply it inside or outside the tank without tape, glue, or tools. When you move the tank or want a new look, simply peel it off – zero sticky marks left behind. Ideal for renters, temporary setups, or hobbyists who like to redecorate often
• Premium PVC Material : Made from durable 2mm PVC, this aquarium decor background survives accidental scratches, water splashes, and daily handling. Unlike cheap paper posters, it wipes clean with a damp cloth and does not warp from humidity. The black surface effectively blocks light from behind the tank, reducing algae growth while hiding unsightly filter tubes, heater cords, and wall stains
• Creates Instant Depth & Calmer Fish: A black fish tank background transforms the look of any aquarium. It creates strong visual depth, making bright fish like neon tetras, guppies, or angelfish pop against the dark backdrop. Plants appear lusher and greener. More importantly, it blocks external light reflections and sudden movements outside the glass, giving shy or easily stressed fish a more secure, natural environment. Your tank looks professional while your fish feel safer
• Simple Bubble-Free Installation: No Experience Needed – Clean the glass surface, spray a thin layer of water, peel off the protective film, apply the static cling wallpaper, then use a flat card or squeegee to push air bubbles to the edges. The water layer lets you slide and adjust the position before it sets. Even first-time aquarium owners achieve a smooth, wrinkle-free finish in under 10 minutes. No special skills or tools required
