Things You'll Need
- Plaster of paris
- 1 coral mold
- Nontoxic, water-resistant paint
- Paintbrush
- Sealant
Instructions
Pour the plaster of paris into the coral mold. You can find coral molds in most craft supply stores. Use plaster of paris because other types of plaster or molding agents have toxic chemicals that can affect the fish.
Allow the plaster to dry completely. The time for this varies upon the size of the mold and the brand of plaster of paris you use.
Remove the coral from the mold. Take care not to break or damage the coral when removing it.
Paint the coral as desired. Coral is naturally bright with lots of pink, blue, orange, purple and green hues.
Allow the paint to dry completely before continuing. Apply more coats as needed. Allow each coat to dry before adding an extra coat.
Cover the coral generously with sealant. The sealant protects the fish from the paint and keeps the coral paint vibrant.
