The Tropical Rainforest Vivarium

Humidity is the whole game for frogs and crested geckos, and the two cheap ways to get it wrong are a screen cage that can't hold it and a sealed tank that turns it into mold. This course builds the third way. You'll learn why a front-opening glass terrarium with a partly covered top is the standard, how the two-to-three-inch hydroball layer, the mesh barrier, and the access pipe keep water where it belongs, what goes in the ABG mix and why charcoal keeps soil sweet, how springtails and dwarf isopods become the cleaning staff before the animals arrive, which bromeliads, vines, orchids, ferns, and mosses live at each height, why a water feature deeper than an inch or with steep walls drowns a clumsy frog and how to build one that doesn't, how a high-pressure mister on a timer delivers short bursts two or three times a day, why surfaces should dry between storms, what a Ferguson Zone 1 UVB tube looks like and why dappled is the goal, why 80°F is a hard ceiling for animals that cannot sweat, how to anchor manzanita, ghostwood, and cork and build sleeping perches, how dart frog colonies are housed and when wrestlers get separated, why nocturnal geckos and tree frogs are never woken by day, how to culture fruit flies and shake-and-bake them in calcium and vitamins, why weekly Vitamin A prevents short-tongue syndrome, why only conditioned RO water and wet nitrile gloves ever touch an amphibian, what the daily skin and body-condition audit catches, and how to find an ARAV amphibian vet.
