i got ICK the second time ever, 3 days ago. i treated my tank after i noticed one little spot on my one guppy, before it got any worse with "quick cure"... this morning i woke up disapointed that the spots are still on my fish after treating it for 3 days (the max dosage)..my fish seemed to be getting worse when i watched it this morning.. he also started rubbing on the gravel, and not eating... but tonite i noticed that all the spots are away now! I just dont understand how in 12 houres later my fish has no spots, and is eating again!... could it be cured that fast? i guess i was just expecting it to get slowly better each day... but BAM it happed all at once!... i heard ICH goes in cycles... could the spots be gone because they are falling off into the gravel as part of its "ICH" cycle?
