Purple tang markings

[Tyberzann]

Good evening all,

It appears I am cursed when it comes to purple tangs.

I have had issues getting these tangs through qurantine so I decided to purchase a pre qurantined fish from my local lfs.

The fish has had 2 treatments of prazi and a fully copper treatment before being moved into the stores displays. All his fish go through this.

I now have the tang home and have placed It into an observation tank on its own with some rubble from my display.

I have had the fish for 2 weeks and Its showing some weird markings and is quite twitchy.

It eats extremely well and is gaining weight but the marks concern me.

Any idea if its ich, or maybe some viral nodes.

I see ick on the dorsal.
I see marks where it fell off.
Looks advanced.
It’s an ick magnet fish.
Hopefully I’m wrong.
LFS quarantine is no guarantee.

Looks like ich to me as well - mucus plugs can look like this, but those don’t grow on the fins.

Ich is difficult for dealers to quarantine for because it takes a full 30 day treatment, and they usually don’t want to spend that much time.

A SIGN OF ICH. You will need to place fish in Quarantine tank and treat with Coppersafe or Copper Power at therapeutic level 2.25 for a FULL 30 days (do not interrupt this 30 day period) monitored with a Hanna Brand copper test kit- No API brand. Also monitor Ammonia levels while in quarantine with a reliable test kit and add aeration during treatment using an air stone. All other fish in with it should also be removed as they have also been exposed to the parasites and placed in quarantine tank.
The display tank will have to be kept fishless (FALLOW) for 6-8 weeks to assure the existing parasites go through their life cycle without a host fish and die off. Inverts and coral can remain in the display (not treatment) tank during fallow period.
A quarantine tank can be as simple as a tank from a second hand store, a Rubbermaid type tub or a starter kit from Walmart which most of the needed essentials.

Its in a qt and has never been in the display so that is not a concern.

Will look to start copper.

 

[Tyberzann]

Quick update, so far the tang has been in 14 days of around 2.3 ppm copper power.

Has been a slight reduction in his eating of frozen food but seems keen to eat nori, so try to keep him stocked up on that daily.

Planning to go the full 30 days as its pretty clear he has some parasite, then ill do a massive water change give him a week to rest and do prazi as a precaution.

Shame its come to this as he was meant to be pre qurantined, but can never be sure.

Have the spots reduced in number over this time?

Refresh my memory - was it exposed to other fish while it had the spots?!if so, any spots on them?

 

[Tyberzann]

It does look like there are less spots on the fish, still some nodules though. Hard to get a decent pic. Going to stick it out regardless.

Its never been mixed with other fish in my household so all clear in the display still
