Advertisement I’m not trying to match the environment just making the enclosure similar with living plants and cleaners. I feel keeping them at a relative humidity close to their wild environment reduces stress for any organism. My degree is in Evolution Ecology and Organismal Biology through The Ohio State University. Maybe I’m going a bit overboard, but when we did research at OSU all our specimens had to have enrichment in their enclosures. For tadpoles this meant rocks and floating plants. For spiders live plants to anchor their webs to. The specimens seemed to have a lower mortality rate with enrichment. Trying to get as close to any animals natural environment will do nothing but benefit it. They evolved to survive in those conditions and trying to meet them as best you can will reduce stress in the animal.
