I am treating a new pea puffer I got for parasites, it was lethargic and not eating well. I gave it the first dose of paracleanse on Tuesday. I forgot to get the 3rd day dose in yesterday. He is already much more active and eating better. Is it ok to give the 2nd dose a day late or should I just do the water change tomorrow and then repeat in a few weeks for the eggs this round won't kill anyway?
