I've had this pair of false percula for six weeks. They did fine in quarentine. They have been in my display tank by themselves for a couple weeks. Eating good tank raised. Tonight I pulled some algae and treated one glass anemone with AhpsiaX. I turned off all flow to the tank for 30 minutes after using the AphsiaX. When I turned everything back on I noticed one of the clowns kind of shivering then they both were. They look healthy and are eating. Any thoughts? What should I do? Also before the shivering started I accidently turned off the tank lights, when I turned them back on the MH came back on.
