Need Help Saving my Fish!

[Raveness09]

Hi,

One of my tangs has passed away. I have a Hyppo Tang and a Porcupine Puffer Fish that are barely hanging on. They are breathing heavy; the tang has started to develop marks on her face. She is on her side and trying to swim. Also, she is losing her color. We have transferred them out of the tank and isolated the Puffer Fish. We thought he could have affected the water.

To give a bit of a back story, we attained the 2 Tangs (Hyppo and Sailfin) and a Filefish. They were in totes doing fine. We moved them to the newly installed tank and they had been doing good the whole day until now. We have checked perimeters and everything was within the limits. Currently, as mentioned, we have lost one of the Tangs. The second Tang is struggling still, along with the Puffer Fish. The Puffer’s breathing has slowed a bit where it is not accelerated. The Filefish is doing better.

We have checked for spots and it is not Ick. The spots she is developing currently seem consistent to the Tang that passed.

Any suggestions on what we can do? We are trying to keep our little fighters as long as we can.

The Hyppo Tang starts to swim around the quarantined tank and then goes back to lay on her side. She’s trying her best to stay up right.

How long has the tank been set up.

Can you provide the numbers you got from your water test?

Ammonia
Nitrite
Nitrate

What kind of filtration are you using in main tank and quarantine tank?

On the tang looks like hlle scarring - it’s generally associated with stress, water quality, and diet, but isn’t a killer on its own.
How recent were the fish additions? Were they quarantined before addition to the display tank?
