Oh man. I just fed the community tank, went to wash my hands, and came back to what I thought was one of my dwarf gouramis (who has never been anything but peaceful) EATING one of my cories. I had a split second of ohmigodwhatdoido?? Yeah, he was not eating the cory. The cory had burrowed himself into a pile of shrimp pellet, and the gourami was just cleaning off his back. I think that took at least a month off my lifespan. I almost threw up.
