I'm going to post two tips for keeping tarantulas each day or so for at least 16 days:
1. Never use sponges in tarantula enclosures, as they are a breeding ground for bacteria. A plain water dish is fine. The tarantula won't drown, they float.
2. Humidity has no use in this hobby, in other words tracking humidity is useless. They do not need humidity, but they do need moisture, which can be accomplished by filling the water dish, overflowing the water dish, and or pouring water directly on the substrate. Misting only dampens the surface.
