Well I went to the store the other day and picked up two cories, and two guppies. One cory died the next morning, had to take it back and get another, well now yesterday another cory died, so there is one left and I cant figure out whats wrong. The LFS checked my water and it was fine, but why did they both die? Both my new guppies are just fine, swimming around and playing. The cory that is left seems ok, but has red lungs...which I thought was from high ammonia levels...but the ammonia isnt high in my tank as it is cycled properly. Any ideas? should I get another cory from this same LFS?
