The other day I noticed that the lid came off of the "Three's a Crowd" group jar.  I watched recorded security camera footage and saw a Opossum on the porch of that morning.   Initially I thought there was no harm. Today I noticed that the Narrowmouth is gone. All I can figure is that Opossum took a drink and drank the Narrowmouth by chance :(

Other than that, everyone appears to be fine.  One of the "Strange fish in Bottles" group is on the verge of becoming a froglet (both in the first photo below and in the video clip.) I've decided to name the group in the jar on the right in the below video "Looks like the Originals."
