Hemorrhagic Septicemia

I think we've figured out what got Red Guy, as the others are now showing signs of illness that we would not have been able to see on such an orange fish. The others are growing relatively lethargic and showing signs of red tissue here and there. One little white fish with a red splotch on his forehead now looks like he's been in the sun too long - he's nearly red all over where he should be white! Torpedo has redness around the base of his dorsal fin. No one has any open sores that I can see, which means this bacteria is systemic. That is not good.
