This happened a few weeks ago; but haven't gotten around to posting it. It's been quiet, so maybe this'll spark some conversation
My wife and I were observing our 12 gallon tank, and all seven rasboras were facing us, and not moving; like they were watching us watching them. And they didn't move for something like a couple minutes! How weird!
I mean, when we had a puffer he'd interact with us; as the betta does. Our new betta zooms right to us, flaring away. But other than feeding time the rasboras hadn't really shown an interest in the 'outside world' per se. They haven't shown any since, either.
