All new Tangs Died

Also what is salinity?

 

[ScottB]

45 mins of drip sounds good enough for all but the largest of variance in salinity.

What is your salinity and how much different was that to the donor water?

If that was an API kit for ammonia, you are likely fine. They always show some ammonia.

Is the Regal eating?

 

[Raege]

I agree ammonia should be zero. May have cpl things here with fish health coming in and bio filter not fully developed and couldnt take additions and maintain zero ammonia

 

[Matthatrick]

You have an ammonia reading. There should be no ammonia at all.

Besides a water change, what’s the best way to remove ammonia, can you recommend a supplement?

 

[Raege]

Sea Chem prime can neutralize ammonia

No he has stopped now ☹, it’s really sad
My salinity is 1.026

How long and how did you acclimate?
Also, are you able to get a sample of water to a trusted LFS to have them test and compare with your readings?

your fish most likely died from ammonia poisoning due to being in a very new tank with no where near enough bacteria. Just to many fish to add to that tank so fast. Your ammonia reading was probably much higher when the fish died but it dissipates fast as bacteria process it.

Your test kits are fairly useless for determining if a tank has cycled. Your tank is only cycled enough to process whatever creature or chemical you used to cycle it with, not a few tangs and damsels at the same time. Tanks cycle, slowly as livestock is added and continues to cycle for the entire age of the tank. Bacteria multiplies as fish are added, but not very fast.

This is very common. The parasites on your still living fish is because they lost their immunity from all the stress.

Exactly how did the fish look when you found them dead? Did they have their mouths wide open or were their gills flared out or red.

Were they floating, did they swim around in circles before they died?
Just saying a fish died doesn't mean much when determining the cause of death.

 

[Matthatrick]

I just re took my salinity and it’s on 1.035.
Help, how do I drop this? Can I replace 50 litres of water with 50 litres of RO water

 

[ThePurple12]

it would probably be best to bring it down slowly so that your fish aren't hurt by the shock.

To climitize I dripped my tank water in over a 45 min period and then introduced them.

Some will disagree with me on this, and thats fine. But IME drip acclimation is a fish killer, especially tangs.

Here is what works best for me, by far, and again Tangs are the fish where I see the benefits most.
1. temp acclimate 15-20 minutes in a closed bag
2. prepare a container with aerated, temp matched, salinity matched water. Most fish are shipped at about 25-30 ppt. I don't sweat the decimal points here, the idea is just to get some nice clean low salinity water.
3. Open the bags and IMMEDIATELY (within <10 seconds) remove the fish from the nasty bag water and put it IMMEDIATELY in the water you've just prepared.
4. add salt water slowly to adjust the holding tank to normal salinity over the next 2-12 hours.

This way, the fish are never exposed to toxic ammonia that accumulates in the bag and is made toxic by pH effects on opening the bags.

Again, there is a lot of variation and some will disagree with my procedure. But I can say with absolute certainty that everytime I've tried to drip acclimate a Tang, they've showed distress during acclimation. Heavy breathing, lethargy, etc. With the method I described above, they are immediately happy and swim and breathe normally.

I would recommend a big wc. You could probably do 10 gallons of just rodi to fix the salinity

So here is some pics of my picture shy fish lol.

You’re going to need a bigger tank for that V...

Agree that the salinity is probably the big stresser in this case. Water changes by removing tank water and adding RODI to bring the salinity back in line slowly are my thoughts.

 

[vetteguy53081]

You have an ammonia reading. There should be no ammonia at all.

Salinity was my suspect and you will have to bring it down slowly, not abruptly. I would pull 2 quarts of water out every 2-3 hours and replace with RO water until youve reached at least 1.028. 1.025 is your goal.
Acclimate by placing fish in small tub or large bucket and add a cup of tank water every 15 minutes 6-8 times (1.5-2hrs) and net or release via large cup into display in the future

 

[Dilan Patel]

I know I will do whats best for the fish when that time comes.

 

[Matthatrick]

The evolution aqua 1200 is 116g. I don’t understand why aquarium manufacturers use random numbers. Why not use the actual volume of the tank?

I think the 1200 is the length of the tank

What size tank is this in? Not sure how it’s related to the OP though...
