Cause

  • Calcium or vitamin D3 deficiency
  • Lack of exposure to UVB

Treatment

A kinked or wavy tail and depleted calcium sacs are two surefire symptoms of MBD. You can check the gecko’s calcium sacs by looking at the underside of her throat — if you can see two white ovals there, her calcium sacs are fine. If they are very small or nonexistent, you have a problem.

UVB is not required for mourning geckos, but it does a good job at preventing and healing MBD. If you’re not using a UVB bulb, install a 2% or 5% UVB over the terrarium mesh. If you have a bulb, check to make sure it hasn’t expired (they expire and need replacement every 6 months).

Offering a dish of calcium powder with vitamin D3 and dusting feeder insects with the same also helps restore bone density and prevent future cases of MBD in your colony.
