Zoa help please!

[bobonakamoto]

These things are crawling on my zoas and making them close. I ordered Bayer. Am I going the right direction?

Those are somewhat harmless flatworms. I don’t think that is the issue with then closing up to be honest. What are your nutrient levels, do you supplement iodine ever, temp, flow, lighting?

They are a new colony currently in my QT tank. I wasn’t sure if they are still getting use to new home or if the pest are bothering them.
