Madagascar Hissing Cockroaches (Gromphadorhina portentosa) are fascinating and low-maintenance pets. Here are some guidelines to ensure their well-being and provide optimal care:

Habitat:

• Enclosure: Use a glass or plastic tank with a secure lid to prevent escapes. A 10-gallon tank is suitable for a small group of hissers.
• Substrate: Provide a substrate layer of peat moss, coconut fiber, or a mixture of both. This will help maintain humidity and create a comfortable environment.
• Temperature and Humidity: Maintain a temperature range of 75-85°F (24-29°C) with a humidity level around 60-75%. Use a hygrometer and thermometer to monitor these conditions.

Feeding:

• Diet: Offer a balanced diet consisting of fresh fruits and vegetables, such as apples, carrots, and leafy greens. Commercial cockroach dry meal can also be provided as a supplement.
• Water: Supply fresh water in a shallow dish or water gel crystals. Ensure it is accessible at all times.

Environmental Enrichment:

• Hiding Places: Add hiding spots like cork bark, cardboard tubes, or egg cartons. These provide shelter and simulate their natural habitat.
• Climbing Surfaces: Place branches or cork bark in the enclosure to offer climbing opportunities and create a more engaging environment.

Maintenance:

• Cleaning: Regularly remove uneaten food, feces, and molting exoskeletons. Clean the enclosure every few weeks using a mild, reptile-safe disinfectant.
• Handling: While Madagascar hissers are generally docile, it's best to minimize handling. If necessary, handle them gently and avoid sudden movements.

Additional Tips:

• Avoid keeping hissers with other insect species, as they may harm or outcompete each other.
• Provide a day-night cycle by using a light timer. Aim for 12 hours of light and 12 hours of darkness.
• Observe their behavior regularly for any signs of illness, stress, or unusual behavior. Consult a veterinarian experienced with invertebrates if needed.

Remember, proper care and attention are essential for the health and well-being of your Madagascar hissing cockroaches. By following these guidelines, you can create a thriving and enjoyable environment for your fascinating insect companions.
