Tangsssss!

What copper product and what level?

What do you use as a test kit for copper?

If you have rock it can also absorb some copper. I am assuming you have rock?

Did your water turn cloudy at all?

How long were the fish in copper? Copper is toxic and fish should not be exposed to it for prolonged periods. Only for the treatment time needed.

wow thats a lot of questions!

i use the seachem cupramine

i have the salifert copper test kit but never use it

yes i have rocks, it is a FOWLR tank

water turn cloudy for 1-2 days

the fish was in copper for like 2 month until i add in carbon to remove prazi

Since you don't test and have rock, it is likely the copper concentration is enough to suppress disease but not cure it since rock absorbs some copper.

Mixing copper and prazi, probably even more so in a cycled DT can cause a bacterial bloom. It sounded like this happened from the cloudiness. While the spots are indicitive of some disease (maybe ich?), it is likely the fish suffocated. I don't know why the powder lived, maybe the sump has greater oxygen since skimmer is nearby, not sure.

Copper is a 30 day treatment, carbon does a very poor job at removing copper. It is likely there is still copper in the tank.

You really should have a separate QT tank and not be using the DT as one.

@Garland Goodwill that is very important “You really should have a separate QT tank and NOT be using the DT as one.” Unless you can’t catch a fish out using the DT as a QT is catastrophic. My guess is like @Tamberav all the oxygen was sucked out of the tank. I think it would be best to:

1 Remove the PBT and place in a QT system
2 Do the 76 day fallow up period (test regularly)
3 (if you can) Remove all rock clean as much as you can and place it in a separate saltwater station (big container) with some high flow, do a massive water change to the station, and then let the rocks sit for a few weeks and the add them back to the tank.
4 Add some fish before adding back the PBT or the Clown.

i also dk how pb survive, the skimmer was off that time

Copper for 45 days, why not?!

I have read a lot regarding quarantine protocol. It seems the current recommendation is copper for 30 days, change water, treat with antiparasitic and antibacterial, watch for two more weeks and your good to go. My question is why not treat with copper for 45 days and skip the two week...

Is this really true that fish can live in copper in their whole life

No. I don’t know too much about copper cause I hate it, but in the post(s) it said 90 days. Copper to some levels isn’t necessarily harming the fish, but the constant adding and one dose being a bit much or not adding regular extra oxygenation and observation can cause the fish problems. And in many cases (and in the rookie mistake that even experts aren’t above) kills the fish.

No, it is a poison. It just kills the parasite before it kills the fish.

Long term copper can damage organs as well as supress the immune system leading to bacterial infections.

There are many publications/articles on the toxicity of copper and fish.

Tangs are high oxygen demand fish. Do not turn off the skimmer, if it is overflowing from something, remove the cup so it overflows into the sump.

that time i off it is because i dont want the copper to get sucked all up into the cup
never thought of opening the cap

Hi guys, my tank is empty right now and I want to buy more tangs. Currently, i have a powder blue tang in my sump which i move it there from the display tank about 2 months ago. I had move it to the sump is because it is a bully to other tangs. If i want to add more tangs like a clown tang, should i move the powderblue when the clowntang is in the main display?

How did you treat with prazi (how long and at what dosage?)
PBT generally not susceptible to flukes but rather velvet disease.

Having many tangs and for years- Clown and sohal tangs are the nastiest you will encounter. In many cases with tangs, the prettier they are is the nastier they are. Acclimation box better than sump for holding area. Make sure they are quarantined- they are the worse with getting an ailment when newly acquired.

The water flow down the return pipe will get oxygenated. That is why the PBT survived and other fish in the DT died. From what you told us, barely survived.
LR absorbed copper and will release it when the pH is a little low, like at night. That is why LR that were copper treat will never be able to be use in reef again.
You can do an acid wash and dissolved a layer of rock; this may be able to get most of the copper out.
Your tank got sick likely because there are too many aggressive fish. They are all stressed out. The copper suppressed their immune system and they died or get sick. I was never a "chemical and toxin" man in keeping my reef so I don't know what else to think you should do.

i just treat it to full dosage and next day fish started dying.

You want to consider useable gallons. Praxi is best used at 80% of recommended dosage as your water volume is reduced by rocks and other components. Prazi reduces both oxygen and appetite and should be dosed for an 8 day interval, water changed and one more dose for an 8 day interval with air stone added for added oxygen.
