Can leopard geckos or crested geckos live together?

Updated

Short answer: Best kept alone. ReptiFiles does not recommend housing leopard geckos together, and does not endorse it for crested geckos either. Two males will fight; a male and female will breed. Two females introduced together are the likeliest to work, in a much bigger enclosure. Separate them at once if you see tail or crest biting or weight loss.

Leopard geckos

  • Not recommended, especially for a first gecko. Geckos kept together can drop tails, get severe bite wounds and even broken bones. Males are most at risk, but females fight too.
  • Male and female only if you want eggs.
  • If you try a group anyway, use a bigger enclosure so each gecko has its own territory, and be ready to move them to separate enclosures the moment they fight.

Crested geckos

  • Two males: never. Males fight; ReptiFiles describes a breeder whose juveniles grew into males, and one was killed.
  • Male with females: they will mate and lay eggs, and it needs close supervision.
  • Two or more females: the likeliest to work, if introduced together and similar in size.
  • Space: at least twice the volume of an 18 × 18 × 36 in enclosure (11,664 cubic inches); about 23,000 cubic inches is recommended.
  • Cut competition: several food and water dishes, more than one basking spot, and plenty of cover to break lines of sight.

When to separate

Tail nipping, crest biting, a dropped tail, weight loss or unusual behavior. Move them into separate enclosures straight away.

Questions

Can two leopard geckos live in the same tank?
ReptiFiles does not recommend it, especially for first-time keepers. Housed together, leopard geckos can drop tails, suffer severe bites and even broken bones. When in doubt, keep one gecko per enclosure.
Can two female crested geckos live together?
It is the pairing most likely to work, though still not ideal, if they are introduced at the same time and are similar in size. The enclosure needs at least twice the volume of an 18 × 18 × 36 inch tank.
Do geckos get lonely on their own?
ReptiFiles' advice for leopard geckos is that a gecko housed by itself will be fine.
