I am not sure but I think we have a bronze cory. It lays on its back or side and is still alive! I know it's not normal, but don't know why it is doing this, or how to help it. Today we thought it was dead because it was still layin on its side, and doesn't move around as often. But when we went to get it out with the net, it started swimming around again. We also have a red-tailed black shark. I need some information on what's going on, if anyone knows or might have an idea on what is happening or how to help the fish....could it be possible the red-tailed hurt one of the fins on the cory??????
