I have a common goldfish that I got a while ago, it lives in a 10 gallon tank (I only put about 8 gallons, though) and I did (about) a 40% water change, and something happened, and my fish got ick. I bought a bottle of Methylene Blue, but because I am living in a non-english speaking country, the bottle says nothing about how much I am supposed to put in, and for how long. Does anybody know? Thanks.
