Using the Metal Tropical Fish Sign is easy. You can hang it on a wall in your living room or patio, or place it by the poolside. For hanging, if you've requested mounting holes, simply use nails or screws to secure it. When choosing a spot, make sure it's visible and fits well with your existing decor. As for maintenance, since it's made of metal, it's pretty durable. But in outdoor settings, you might want to clean it occasionally with a mild soap and water solution. Avoid using abrasive cleaners as they can scratch the surface. If you notice any rust spots over time, gently sand them and touch up with a matching paint. Keep in mind that although it can withstand different weather conditions, extreme cold or heat for long periods might affect its appearance, so try to place it in a sheltered area when possible.
