I found out that I had two that have entered the froglet stage with a third one soon, all members of the  "Strange fish in Bottles" group.  An observation that I've seen multiple times is that tadpoles that don't have to share a container tend to develop better as shown in the below photos.  I've decided to name the tadpole shown in the video below (and in the first photo) "Only Child."

The grey fur resident made a surprise inspection of the container i grabbed to transfer the froglets into.  Also, I gave the "Pond" group Narrowmouths a hiding leaf that they seem to be enjoying.
