Hello I recently added a group of anthias from a friends tank to my Dt. I’ve seen the tank/fish multiple times and we’ve traded before so I don’t qt stuff we swap. 2 days ago I noticed one of the anthias straying from the group with popeye and hiding in the rocks when I got a good look at him he was pretty beat up. I figured the popeye was because I just installed a new skimmer that was dumping crazy micro bubbles into the tank. Not that he’s so beat up I believe it was flukes. I moved him to a different tank but he did not make it. Today I noticed a black dot on my foxface and my hippo looks like it’s been scratching with specs near his tail. I dosed prazipro and have airstobes going in the tank. When I dosed prazi there were white specs floating all around almost instantly. Is it safe to assume it was flukes and continue the dosing routine or could I have just killed a bunch of random other things in the tank? Also my tank is 180g to do a 25% water change multiple times is a pretty big ordeal using 5 gallon buckets. Am I safe to change a smaller amount let’s say 20 gallons each time? The tank has been up and running for 15 years and this is my first encounter of this sort. I appreciate the help greatly!
