Since the holidays I've been taking extra care of my frogs. I've become rather tedious about misting every day and feeding every other day. I've gotten almost everything calling. This morning I woke up around the time my lights came on and I heard a sound I've never heard before. It sounded very much like a duck quacking. It was quacking with about the same time differential that my bassleri calls. Then I heard the bassleri chime in and the quacking stopped. I'm wondering if this was my bassleri warming up, or if my valerioi were calling before they went to bed (I've never heard my valerioi call). I guess long story short, has anyone witnessed a bassleri quack rather than chirp?
