Aquarium decor does not need to be expensive or new. In fact, if you have fish tank ornaments that are old and have flaking paint coats, you can always try to repaint and make them look like new. To do so, follow the instructions below.

Step 1 - Find Paint That is Safe for Fish

Not all types of paint are safe for fish or appropriate for prolonged exposure to underwater conditions. A good example is an epoxy paint, which is considered toxic when wet but is fairly safe to be submerged in water when thoroughly dried. Pure acrylic latex paints can also be used. However, this type will not last as long as epoxy paint.

Step 2 - Prepare Your Work Area

Whatever type of paint you plan to use, make sure that you cover the area of the floor where you will do the paint job. Use old newspapers. If you are going to use spray paint, you may want to cover a portion of your walls too.

Step 3 - Dry the Decor

After painting the decor, make sure that it is thoroughly dried before putting it inside the fish tank. Read manufacturer's instructions to know how many hours you need to let the paint dry.

By following these steps, you will have painted aquarium decor and given your tank some new life.
