Now all of my cories have passed away. I have done some reasearch and I think my fish have gotton the illness HEMORHAGIC SEPTICEMIA (sorry it is in caps- I copied it from the website and it was in caps there. I didn't want to type the long words) at the fish store I got them at. They died so quickly because of the stress of getting in a new tank plus the illness. For the pictures.... use the flash? And just angle it up, use a higher ISO (I figured out how to do that) and use macro mode?
