I recently moved a 13 month New River to larger quarters, a ten gallon tank by himself. The frog has since been eating voraciously and I've also noticed that he has become more active than he used to be, constantly exploring and climbing the walls. It's been a few weeks and I've also noticed that he's not quite as plump as he used to be. His lost a bit of the paunch on his sides. I don't know whether to attribute this to increased activity or parasites. I've been pouring in the fruit flies. Do you think that I have anything to worry?
