What should you pay attention to when decorating an aquarium?
When choosing decoration for your aquarium it is important to pay attention to the following aspects:

Suitable materials:

Aquarium Resin and Synthetic Resin : Non-toxic and safe for fish.

Colorful decorations can be attractive, but make sure the paint is non-toxic and won't come off in the water. Choose decorations that contain water-resistant and fish-safe paint.
