My yellow coris wrasse seems to be flashing a lot lately. Some of it looks like territory marking like when the cleaner shrimp was next to his cave. He does it on the sand and rocks. Seems perfectly healthy right now though with activity and eating. Only other fish in the tank is a red fairy wrasse that is not flashing and seems healthy presently.

Normal wrasse behavior? Flukes? I would say I see him do it maybe 8 or 10 times a day.

Some wrasses feed by sort of swiping their heads in the sand, so you need to try figuring out if it is that or true flashing which is often a sign of flukes. If you end up thinking it is flukes, Prazipro, with good aeration is well tolerated in most reef tanks.

Can you use prazi in the DT with coral and inverts if you remove carbon?

Yes, turn off skimmer and add an air stone. Sometimes SPS react to the added nutrients and some people have reported issues with clams and feather dusters, but I’ve not seen that.

Thank you will do. So skimmer off all 2 weeks for 2 doses if needed?
Most people just continue to run their skimmer but don't collect the skimmate (if you model can do that). Otherwise, yes, turn it off for two weeks.
