This was after the second dose of prazi pro when he was in my 400 gallon reef tank ! My other fish were fine but they went through something similar but most of them have been put in a qt for a month are two and are now back in the tank ! Only thing that died this time was a white tail bristle tooth tank and that Achilles!
Yeh I don’t know if it’s velvet ! I think it might be something else unless the rest of my fish are immune to it ! I had my big blonde naso and a big mag foxface get it about 4 or five months ago and treat them with copper and reef rally and they got better and showed no signs of it for over a month or two so I put them back in ! Then my Achilles started to get it so I figured I’d treat my whole tank with prazi because it started out looking like flukes but turned to that fast !
What’s weird is I have 2 yellow tangs , a purple tang , blonde naso , a mag foxface , parrot koi that are all about 5 inches or bigger and then a couple wrasse and clowns that never get affected but did lose a bunch of Anthius tho !
