Ok so put your pitchforks away and hopefully you can shed some insight (I didn't quarantine, there, it's out of the way).

Dropped by our LFS after finding out they got a fresh shipment in. This included captive bred fish from Biota. We picked up a juvenile tang and a mandarin goby. After talking with the folks there we liked the idea of captive bred for having a VERY small chance of any issues or parasites. Obviously they didn't say outright "don't QT", but i felt in this circumstance since they'd been in the store for 24hrs in a copper dosed tank and captive bred that things would be fine. There would be such a slim chance they could have picked up anything.

He's healthy otherwise, pale in color (still very young and small) but picking away at rocks for algae, not breathing hard or showing any distress. We did a long acclimation drip. It's day 2 and we've noticed our Yellow Tang rubbing rocks. I do not see any signs of ich anywhere. He will swipe by a rock on both sides, and sometimes he'll brush his tail on rocks too. After doing some searching everything keeps pointing to ich or flukes. I've not seen any indications, but know some have said it could be in the gills in the early phase.

I'm starting up a QT tank as i type but i seriously doubt I'm going to be able to catch him without destroying my tank. I know my other fish could be at risk now too, and that feels bad. Should I take the easiest route first and feed API general cure + focus to rule out flukes?

In the meantime I'm going to make sure to keep them happily fed and low stress.

You can treat for flukes using Prazipro, right in your display as long as you are careful, make sure it’s got good O2 exchange, and keep an eye on everything.

If it’s anything else (ich,velvet,etc) you’ll need to catch and treat all fish in a QT... and run your display fallow to starve it out.
I’ve been there, it’s a pain but doable.
 
Before you considee dosing your DT you need. To consider a few things. 1) do you have coral 2) any inverts 3) some of these meds will attack anerobic bacteria and could impact your bio filter.

If one fish is rubbing i would strongly recommend catching one and doing a FW dip to check for flukes. Ich is also a real possibility too and you should get a QT set up to treat all of your fish and realistically prepare to let your DT go fallow for 76 days. If you choose to attempt the Maintenence route if it is ich you will always wonder if a new fish will fall victim and perish. GC will treat flukes if you treat the tank, feeding GC really is only effective for internal parasites,and copper for ich. Im not sure about how to treat the mandarin safely but someone will chime in.

Consider this a lesson, eradicate the parasite from your DT and keep moving forward. I wish you the best of luck.

I agree with the comments already posted. Good luck.

Any special treatment for a Mandarin? I tagged you to give the OP advice on that. If you dont mind.

I missed that, CP is your best bet. The issue is keeping it feeding during medication, and sourcing CP. Live pods will need added every couple days.
 
Problem is that the wholesalers don’t keep the Captive bred fish in isolated systems with strict practices to avoid contamination so they are exposed to everything a WC fish is. I actually think CB fish are more likely to get infected because they have no immunity built up to anything.
 
A big thank you to everyone responding so far. I ordered some GC and Focus last night. Should have it wednesday. Both local stores didn't have it in stock. Will try this route first while monitoring for any changes.
 
Just want to clarify... I would not suggest treating your display with GC. Feeding GC will help if he has internal parasites... but not so much for flukes (if that is why he is rubbing). If he has flukes, it’s best treated by medicating the water column.

Praziquantel (Prazipro) is reef-safe with caution, and should not harm corals or inverts provided care is taken while administering. GC is NOT advisable for use in a reef tank if it is not bound to food.

I highly +1 to the advice regarding performing a freshwater dip to confirm/rule out flukes if possible.

Prazipro would not harm the mandarin either, if flukes are confirmed.

Good luck, Hopefully you can get to the bottom of it!
