This helps your fish stand out and creates a more secure, calming home atmosphere for your aquatic pets. Safe material: Made from PVC, this background is safe and odourless for a healthier viewing experience. It offers strong shading and tear resistant properties for long term use, while ensuring safe and easy installation.

The result is a tidy, professional appearance with minimal effort. Use scenarios: Refresh an existing tank: a dull background to create more depth and draw attention to your fish and decorations.
