I was emptying out the FBT's water and ran across this little round thing (sorry the pic is bad, my phone takes crummy indoor pics). I thought it looked like it had two micro black dots like eyes, and looks similar to posted pictures here...or is this just really well formed refuse? If it is an egg, I dumped out all but like 1/4 to 1/2 cup of water before I saw it- there is just one...how do I go about caring for it? Also, provided its an egg, does that mean there are more that the frog is going to lay? The one I think is a female is spending most of the time in the water.

If it's not I will feel a bit silly posting frog manure lol...
