3 tangs died. I believe they had internal parasites

[Miami Reef]

This is in a QT.

They all start out fine. Eating with great appetite, but they continue to lose weight with a pinched stomach.

I feed 2 times a day. It’s impossible that they are starving to death.

I didn’t lose all the fish at the same time. They died about 2+ weeks apart.

All the fish were treated with copper, metro, and prazi in the water column.

I highly doubt it’s tang aggression. I never saw aggression, and they never died with bite marks. Always with pinched stomach.

Is it possible for an internal parasites to spread so rapidly?

 

[Miami Reef]

I noticed my last tang staying at the bottom and VERY skinny. I had a feeling it was a goner. When I saw it dead this morning I was upset. It looked white and discolored. Extremely skinny.

Did you use all three treatments at the same time?

How big were the fish ?How long did you have the fish? What, how much, how often were you feeding?

 

[BoneDoc]

I would remove the copper and metro and stick with prazi only. Copper is an appetite suppressant.

The fish were very small. I had the fish about 1.2 months in QT. I fed a lot of different foods: live blackworms, LRS frozen, angel food, spirulina mysis and brine. I fed 2 times a day at least. Sometimes even up to 4!

 

[Miami Reef]

The treatment was done at the same time (copper metro prazi) no bacterial bloom nor ammonia. Fish all eating with gusto.

My last fish died 2 days after being transferred into observation.

I’m starting the metro and prazi food soaking.

Reading HumbleFish or the Marine Collector, it sounds like they do copper first then prazi/metro later, but NOT all three. In the future, I would advice against doing all of them simultaneously.

Were they all voracious eater but still loose weight over time? Do you have pictures of them before their demise and earlier on in the QT process? A lot of this doesn’t quite add up. I’m sorry for your loss nevertheless

1. What others have said - best not to do all 3 at once.
2. IME. -internal parasites will not kill fish 'quickly'
3. Were they thin when they arrived? Or only after you had them for a time. If they were EDITED - NOT - in bad condition when you got them - it could have been the medications causing the problem. The likelihood (if they had internal parasites) - is that they would have looked sick when you got them
4. Were you checking Ammonia, etc? copper levels?

That is very stressful for the fish to do all at once.

This was the fish about a month ago:

It appears it slowly got skinnier and skinner. Up until last week it looked deathly skinny and I even predicted it would die.

The picture above was August 30. That was when it was its biggest.

Is that the QT or your main display tank?

About the copper. I tested daily with Hannah checker. 2.5ppm

QT

Sorry for your loss. I don't QT fish anymore but I don't think you are meant to have sand in the QT with medication, it messes up the copper concentration
I've become a fan of observation tank method and then into the display tank 1-2 months later if they are doing good. No medicating

 

[mike89t]

QT

And how were you measuring your copper levels?

This was the observation tank. I did not have rocks nor sand in their tank. Ammonia was 0 with the seachem badge.
