Prevention Strategies:

  1. Proper Ventilation: Ensure your gecko’s tank has adequate ventilation. Use a tank with proper air vents or consider adding a small fan to promote air circulation. This helps in reducing humidity levels and discourages mold growth.
  2. Optimal Humidity Levels: While crested geckos require high humidity, it’s essential to strike a balance. Invest in a reliable hygrometer to monitor humidity levels in the tank. Maintain humidity between 60-80%, as this range provides the necessary moisture for your gecko without creating an excessively damp environment conducive to mold growth.
  3. Suitable Substrate: Choose a substrate that doesn’t retain excessive moisture. Coconut coir and sphagnum moss are popular choices as they retain moisture without becoming waterlogged. Regularly spot clean the substrate to remove any waste, uneaten food, or shed skin.
  4. Proper Cleaning Routine: Establish a regular cleaning routine for your gecko’s tank. Remove uneaten food, clean the water dish daily, and spot clean the enclosure to prevent organic debris from accumulating. Perform a thorough cleaning and substrate change periodically, ensuring you completely dry the tank before reintroducing your gecko.
  5. Naturalistic Cleaning Crew: Consider introducing natural cleaning crew members like isopods and springtails. These tiny organisms help break down organic matter, keeping the enclosure clean and reducing the chances of mold growth.

Can Mold Kill a Crested Gecko?
