My tank has been up a few months. My water is good for a new tank 35 salinity, alk 9.2 PH-8
Calc-420 Mag-1400ish. Temp stable 78-79. My zoas (in tank about 4 weeks) were fully open. Last week they closed up and seemed ticked. I did a 30% water change and about half of them opened up. Now they seemed ticked again a week later. I dipped them in RX and diluted Hydrogen P. Seemed better(ish) tonight I noticed one single "sweeper" arm? coming out of a few heads. Is this a parasite, spider? Or maybe pox?
