I don't have GC or Focus on hand. I've had them for over 5 months, other than the Flukes when I first got them, they were doing fine and I was about to move them to the big tank, but then this happened. I never noticed any pooping, I'm not watching them 24/7 but I do see them a ton since they're in this room where I am most of the time, I'm watching them destroy the seaweed right nowI would try feeding General Cure + Focus, for at least 10-14 days. Can go as long as three weeks if needed. Tangs are poop machines, if you haven’t seen them poop than there is definitely something going on there...
I usually do 2 scoops GC + 1 scoop focus per 1 tablespoon frozen food (frozen mysis is easier to medicate than nori) and feed at least twice a day. Just small amounts at a time, only as much as they can eat so you don’t muck up your QT.
I thought maybe I was under feeding them and didn't realize it, I tried giving them NLS before but they weren't interested, seaweed is all they want! I started making sure they always had some available.
I ever see any of my fish poop actually, maybe they're just very private and poop when I'm not around. lol
