Nutom, yeah, I am surprised, usually they go for frozen foods first, then pellets! I will try to get some new pics, I only have a camera phone though. It is funny to see all three at the front of the tank begging for food when I come down.
I agree on the hypo, its something you have to do gradually. I would recommend copper though, cupramine to be exact. Hypo only kills ich (I don't think its 100% effective either) and if your fish died overnight, then it definitely was not ich! Copper kills most diseases, so combined with prazipro for internal parasites, you should be disease free.
