Things You'll Need
- Terracotta pots
- Electric drill with concrete bit
- Rotary drill with grinding stone bit
- Non-toxic silicone
- Lexan or plastic (optional)
Instructions
Secure your terracotta pot so that it can not move. Using your drill and concrete bit, make small holes into the side of the pot. Eventually, the small holes will cave in to create a larger hole. This will create your opening in the terracotta pot. Wetting the pot before drilling will help keep the dust down.
Round out the rough edges with the rotary tool and grinding stone bit. This will prevent the fish from cutting itself when entering and leaving the terracotta pot.
Add a bottom to your terracotta pot if you would like. Place the pot on the sheet of plastic and trace around the edges with a pencil. Cut the shape out and secure it to the bottom of the pot using non-toxic silicone. Let the silicone cure.
Wash the pot using hot water. The terracotta pot can now be used as a cave in your aquarium.
