I have noticed what looks like red cottony tufts of I'm guessing bacteria or fungus in each corner of my court jester goby's mouth. I noticed this 2 days ago and panicked a little, couldn't find any info on it but assumed it to be bacteria so I treated the tank with a low dose of mardel-freshwater. Today my mandarin is exhibiting red streaks on one of her side fins. A little background: I usually keep my tank near 79 F but it got warm where I live and I didn't not realize that this would affect the tank so quickly, it got up to about 85 F for a day. This may be what triggered the onset of this infection. Does anyone know what my fish have? And if so, how do I treat it?
