Hello, I'm in panic. I changed Mozart's water 50% did the usual, add salt (aquarium salt), I added "correct pH" because it was a little high, Jungle Fungus Clear and Stress coat. I did this about an hour and a half ago. I fed him and went down stairs, when I came back up he was just floating in a corner. I quickly got another bowl, with fresh water, added everything but the Jungle Fungus clear and still nothing. Pretty soon I am going to put him in the 10 gallon tank and take out the black skirt tetras because they seem to be doing fine. Please help!
