So this morning, my cleaner shrimp was doing great. He was eating and pretty active. At about noon, I did not "Nano A & B" dosing (I have a 28 G Nano) and now at 3:45 I find him dead by my urchin and Flame Scallop. I know that these two "suspects" are not usually predatory but it there a chance that something may have killed him? I have had him for a year and he has seemed healthy this whole time.

RIP...
