I posted here about a month or two ago about clowns showing some flashing behavior. I did a freshwater dip and didn't see any signs of flukes, and I haven't seen any visible signs of ich. All of my fish and corals in the tank came from a single dealer that does quarantine and prophylactic treatment for ich and velvet. I haven't done separate quarantine.
Tonight I saw that all of the fish are aggressively flashing except for my foxface - this includes a couple wrasses, a pair of clowns, a firefish and a royal gramma. I don't see any signs of ich on the fish. The latest fish to be added were the wrasses and the firefish, which went in the tank a week ago.
I've been having issues with a ton red cyano on my sand bed. Yesterday I did a 10-15% water change and vacuumed the sand bed heavily. I stirred up a lot of stuff. I'm hoping that this is the likely cause. I run a skimmer, a filter sock and have a media cup filled with carbon. The carbon was changed about 5 days ago.
I have prazi. Could I dose it as a precaution? Should I wait and observe a couple of days? Any thoughts? If it matters, I also have some corals - a couple blasto, a birds nest a duncan and a torch. None of them seem to be affected by the heavy sand vacuuming.
