Well, Last night I checked my water parameters and came up 0 for Ammonia and Nitrites (it's already cycled) and pH is 7.0. The tank is 90g and is planted. This morning I noticed my flag tail cory staying near the surface with the thermometer and it's eyes were filled with blood. I lost it's pair a couple of days ago and it didn't have anything noticably wrong with it. The first one would swim and just collapse on it's side, swim for a bit (1-2 seconds), then collapse again. The second one looked like it was having problems swimming as well, but didn't collapse. Any ideas? None of my other cories look like anything is wrong with them.
