The other one got eaten last week. I will try to go this week to get two more. It lasted several months! So it took about two weeks and the frog had eaten the male guppies and one female. But the fun part is, since then, the two females are still having babies. Apparently, I am wrong in what I am calling two females!!! : So, it's like the frog is a farmer. He doesn't mess with the two remaining fish, but eats their babies that one of them is having about once a month. Smart frog!
