Got my trio of Bicolors on Tue. from Bill at Quality Exotics, they look great, and two of them are very active, the third seems to spend most of his time hiding under moss or leaves in their shoebox. I have also only witnessed one of them eating. I realize that this may not constitute a problem in itself, but I would like to make sure they are all staying healthy. What is a good # of FFs to be introducing into the tank per frog daily? I don't want to stress them needlessly with excess flies crawling all over. FYI: the shoebox has a gravel/leca substrate with a couple of pothos cuttings, some sphagnum, and a paper towel for a hiding spot. The temp during the day is a constant 76* F, a couple degrees cooler at night, with an average humidity of 80%.
