Which Reptiles Can Live Together in a Tank?

Most experts advise against mixing types of reptiles in one tank. Although successful mini-ecosystems are seen in zoos, they require large amounts of space, time and research. Some closely-related reptiles can co-exist in one tank if they are closely monitored. Always use captive-bred, rather than wild-caught, animals in mixed tanks.

  1. Anoles

    • Captive-bred green anoles (Anolis carolinensis) and brown anoles (Anolis sagrei) can live together in large tanks with appropriate habitats for each. Green anoles prefer tree-like habitats while brown anoles live on the ground. Both animals eat insects, but may eat each others' hatchlings if given the opportunity.

    Garter Snakes

    • Different species and subspecies of garter snakes (Genus Thamnophis) can live together, as long as they have enough floor space. In an article at PetPlace.com, R.D. Bartlett describes keeping a dozen garter snakes in a 75-gallon tank. Snakes should be fed individually (either with forceps or outside of the tank) to prevent fighting over food.

    Day Geckos

    • True to their name, day geckos (Genus Phelsuma) are different from other gecko species because they are active during the day rather than at night. Choose geckos of similar size and habitat and use a vertically oriented tank. Smaller gecko varieties appropriate for mixed tanks include neons, gold-dusts, blue-tailed and ornates.
