Hello bcut...

Your tank water is a bit acidic for Corys. Ideally, they prefer a neutral (7) pH. But most fish will adapt. Gill tissue is very sensitive and the high acid in the water may be irritating the fish. You can raise the pH a bit by adding some pieces of driftwood and there are products that will raise the pH too. Research some company names like Kent Marine, Kordon, Seachem and Onyx.
