2 days is still short. If dot is ich it will be on fish for 3 to 7 days before dropping off.
Buggers are just hard to see. I purposefully put the QT tank in an area of low light to try and ease them in. I'll keep checking and see if I can catch the same one from above again. They're just skittish when I walk up to them with a light on and dart for cover. The wrasse, meanwhile, isn't the least bit put off by the light lol!
I'm going to stay the course for now. When I fed earlier 4 of the 5 came out and I could se the other one eating some in it's PVC home. If it's ich or velvet, they need to stay in copper. If it's flukes, the FW dip should have helped and tide them over until the general cure kicks in.
And, if all this isn't enough, two of them at least feel well enough to start the dominance dance as I'm watching them just now.
It in copper no fish is ever 100%. Coloration changes happen in copper or in any QT from stress.
Pale and differences in coloration is common.
You need to treat what you're gonna treat and move your fish to a stable cycled QT.
There honestly no way to know for certain what it could be and very few of us have the equipment to bother.
We can sit here and guess all day but only thing I'd recommend is finish treatment and wing it off the copper and start feeding heavy in hopes to boost the fishes immune system.
I love garlic it increases appetite and may help in other ways unknown.
I always use two types of QT tanks.
One for chemical treatment and one that a cycled with live rock where i can watch for a month or more to be certain before introducing to the DT.
Goodluck and please analyze and watch closely for any progressing symptoms.
I actually suggest all natural QT for fish with heavy feedings to fatten up the fish then chemical for last resort but that just my methods.
Goodluck and take your time.
Thanks man. Just trying to do this the right way, for the first time lol! I may just be jumping the gun on these guys, those the spots and flashing do suggest otherwise. They ate immediately, twice the first day and twice on the second before treatment began. Eating wasn't an issue for any of the anthias until today. I just wonder if I should have started off with a dose of general cure before starting copper. In any case, lethargy can be a sign of velvet and flukes. Just not sure which I should have treated first. I'll remove all hiding spots tomorrow and check for spots again.
QT tanks were seeded with filter media that had soaked in my DT's sump for 4 weeks plus a couple of different bacteria's in a bottle. I don't feel like there has been or is an ammonia issue. I manually remove detritus a couple of times per day a short while after feeding.
Eventual plan is to use my 60 cube as a 4-6 week post treatment observation tank but it's currently QT'ing corals until mid-January.
