Ich and a Yellow Coris Wrasse..........

It depends. If you introduced the other fish while the concentration of Paraguard was a bit low due to time spent in the tank, then probably some parasites made their way to the fish skin.

Remember that a quarantine tank is not so big so the fish are very confined and the parasites can find them easily and fast.

If you had put them all together with Paraguard, I might have been a different story.

Did you dose Paraguard right away when adding those fish?

I have been dosing Paraguard daily for the past 2 weeks prior to the introduction of the newly caught fish.

Would 6 weeks of Hypo be enough? Or should I go 8 weeks?
