:that is not what we are talking about. :those python things don't get the last inch or so of water anyway. not worth the effort imo. for aquatic tanks yes because you want to get the 'bad' water from the bottom and you aren't doing a total water change but not when you are talking about frogs. her tadpoles are not tadpoles much longer.
Well I said I wouldnt use gravel for frogs............ :)
