Things have cooled down, and I've returned home.
I have some plausible considerations of causal factors that may have contributed to the demise of Diego.
Today, in the fish tank that Diego previously inhabited, I discovered a deceased 'stinkbug' on the bottom.
Many of you may not know what I'm talking about, so here's a picture of one:
In western PA, at least, we've been plagued by these bugs for the last 3 years or so. Some kind of invasive species...
At any rate, a few years ago, I found a Praying Mantis in my garage, and it was eating a stinkbug. The next day, the Mantis was D.E.A.D. dead!
So perhaps, Diego, being the voracious night time eater that he was, felt the bump & stink of a deceased stinkbug, settled on the bottom of the tank, and inhaled the morted creature.
Death ensued, or at least to be suspected.
