I cleaned out my frogs terranium today, i usually clean it out every three months or when it starts to look gross. Today i was reading the package on the cocunut fiber stuff and it said to clean it out every month. i clean out waste and stuff and I know it just might be saying once a month so I buy more cocunut husk fiber, but I just wanted to be sure. How often does everyone else clean their terranium. (I only have 1 frog so it doesn't get really messy.)
