Since posting I found the source -- a hairline crack in the tank.

Is that something I can seal with caulking, or should I replace the whole
thing?

Absolutely replace it. I would recommend that you shut the water off and empty
it right now. Tonight. If the tank should break, not only will it dump a lot of
water on the floor, but the incoming fill will be running nonstop, flooding your
home. Lots of damage possible.

This is the correct answer. Our tank (forgive the pun) crapped out at
five am after a night at the bar celebrating my sister's birthday...
whole floor on that level was shot and it was an AMAZING mess. Thank
goodness there was a drain in the laundry room or who knows how much
water would have ended up in the basement (the cutoff valve was shot
too, and kept spewing water).
