Iv come to the conclusion my clown has internal parasites (stringy poo). Iv heard diffrent methods of treatment. I cannot do QT howver I only have two clowns and two snails so it’s best I treat the whole tank. Tank is a fluval 13.5 what’s the meat treatment method? And is there anything I can do untill I can get the medication…turn of lights ? Keep feeding etc? Iv hear Prazipro just looking for other ideas
