I have had this ocellaris clown fish for about 2 years ..in the last week or so it looked as though it had a white piece of poo hanging from It ...now it looks lethargic and sets on the bottom horizontally with some labored breathing... She acts interested in food but doesn't eat.... I no longer see a string hanging from her but her pelvic fin is carried close to the body... I have her in a 10 gallon hospital tank and have dosed PraziPro om Monday 2.5 milliters ...Wensday 2 gallion water change and 2.5 milliliters again.... Does anyone have any other advice ?
