Hurricane in an aquarium
I don't know what's going on but they're all dying. Yesterday morning I had 2 danios missing. I finally found the corpses: they'd been sucked up to the intake of the filter and were stuck there, ack, ack. This morning the tetra was gasping its last fishy breath and one of the remaining danios looked very iffy. Another danio was missing but when I started poking around with the net it appeared, very perky. Maybe it was laying eggs, as they are rumored to do often.
I am mystified. Why do my fish die? Maybe I'll just stare at the emptying tank for a while. I'm still missing one dead danio. There's a possibility that Chances empties bleach into the tank during the day--the dogs are very jealous of the fish.
