How do you seal a vivarium?

To seal a vivarium, first ensure all joints and seams are clean and dry. Use a non-toxic silicone sealant around the edges of glass panels, lids, and any openings to create an airtight and waterproof barrier. Allow the sealant to cure fully according to the manufacturer's instructions before adding any substrate or animals. Finally, check for any gaps or leaks once the vivarium is set up to ensure a stable environment.
