I just changed the substrate from gravel to sand and noticed one of my corys had his barbels deteriorated the other two have fine barbels its just this one. What's wrong and what caused it? I do weekly water changes changing 25-50 percent of the water when I had gravel in and thoroughly vacuumed the gravel. The gravel wasn't sharp at all. Should I do anything?
