EVERYTHING DIED. AGAIN. WE HAVE NO ****** CLUE WHY.
keep in mind that the first shrimp died over two weeks after the rest of the fish, so many theories don't fit, because the invert should have died, too. But it was the only thing doing fine. That's what led us to believe it was some type of pathogen that attacked fish, which led us to put only not-fish in there. But that's been shot to hell, too, since the not-fish died. We have a few theories, but all of them are pretty unlikely... for example, heavy metal poisoning.
