I raised my temp up to 84 degrees last night although I'm trying to get it up a couple of degrees (not sure if my heater can accomplish this). I also applied my second dose of Ich Attack. As I understand it, the medicine works slowly, so it may take a week or longer to see a noticeable difference in the tank. All my fish are still active and hungry, but I did notice that more of my fish are scraping themselves against my plants. I'm a little worried, but I won't be too concerned until I start to see my fish lose their appetites.
