I'm afraid my eel might be sick. About a week ago I noticed some of the feeder/filler goldfish were acting strange, like rubbing up against the glass and rocks, so I took them out and put them in a bucket with some medication and salt, the next morning all of them were dead. Yesterday I brought home several more goldfish, one of which I noticed was white on one side (not markings) and looked half dead, so I took him out and got rid of him. Now I noticed one of my eels seems to have a white spot that I've never noticed before, right by his gills, and he looked like he was rubbing this spot on the gravel. Is he sick and if he is what do I do? I put freshwater salt in about a week ago, which I've heard is supposed to help cure diseases, and the medication I have has killed off any fish I've used it on. Can someone please help me? I really love this fish and would hate to loose him. :sad:
