Well, my swordtail after a week is still not eating (he takes the food in his mouth and spits it back out). He is still scraping against the gravel/ornaments and still shows no outside signs of disease. I have been treating with Quick Cure and have done 10-20% water changes per day. I also have cleaned my gravel twice in the past 4 days. I have added salt. Any ideas on what could be wrong?
