Tang Hyperventilating (1 Viewer)

So long as you know your getting good circulation then it would perk up pretty quickly once circulation has been restored. I've had fish spazing out really dizzy and look like barely hanging on then within an hour it's back to normal once circulation restored. Could very well just be a red-herring and the fish has internal/external disease of some sorts.

Difficult to say without knowing exactly how your system was configured before and after than change and just being on a forum.

You mean fresh air circulation? Because Everything in the tank minus the skimmer has been working well, so water circulation was never really lost.
 
Okay if water circulation was never lost then it's unlikely to be low oxygen. I would be extremely surprised ( but since I've never seen your system I couldn't rule it out 100% ) if your system was totally dependant on a skimmer for maintaining adequate oxygen levels.

Likely a red-herring and your fish issue is from a disease or other stress condition.

If fish is docile enough that you can catch if and swish the fish side to side in the water to get water flow over the gills and see if it perks up. This is as close to cpr as you can get for a fish. That is if you still think low oxygen is the culprit. Not being there and knowing your system I couldn't make that judgement with 100% certainty.
 
Just fed it, and it didn't eat. Could stray voltage be possible? I did turn on a new return pump for the frag tank last night.

What other signs could I look for to see if it is low oxygen?
 
Tank temperature higher than normal ? This can reduce dissolved oxygen levels.

Larger fish would be the first but other fish should be showing signs as well if its low oxygen.

If never used one but salifert does make a dissolved oxygen test kit you can call SWE and see if they stock it if you want to totally rule out the possibility. Very unlikely if circulation was never off but it's still possible.

Unless you get zapped when you put your arm in, its unlikely to be a "stray voltage" problem everyone likes to talk about. Current is the problem not "voltage."

Perhaps, you should just "believe" in your fish and it will be OK. Sometimes fish just get sick and die. When did you add this fish?
 
Temperature is actually lower after adding the frag tank.

What is the test for current in the water? I did not get zapped.

I added this fish about 2 weeks before the spring frag swap this year. Don't remember how many months ago that was.
 
I've had fish that ate and looked totally normal one day then dead the next. For sure keep trying to diagnose but sometimes it just happens and can't be explained.

So the frag tank was completely cycled and normal water parameters before adding it online ?

Woke up this morning to find the sailfin tang in my 125 sucked onto the side of my powerhead, and it died within the hour. This has potential to be the worst day ever.
 
Now the story is changing a bit. One large dead fish already and another on its way out? Coupled with the addition of a new tank to the system.

I'm going to guess temp shock or ammonia shock. Have you tested the water? What exactly did you add to the system?
 
Added the 30 breeder tank with a rio 1700 return pump. 30 gallons of reef crystals salt water, that's it. No livestock. Sailfin tang died in a completely different system in the family room. The tennenti is in my 72 in my bedroom.

Temp. went down from around 80 to 78 after about an hour after installing the frag tank.
 
Were the fish purchased from the same place at the same time?

Anything in the frag tank - rock, sand, etc or is it completely empty?
 
I do have an RO/DI system that I use for all of my water.

The sailfin was added last weekend to the 125. The Tennenti was added several months ago to my 72.

The frag tank is empty.
 
Did you recently have your carpets cleaned, spot removers, bug sprays etc.

I've have a buddy that lost lots of livestock due to heavy duty spot remover chemicals/fumes get into the air when they were cleaning the carpets.

Quick sudden changes I always think about in one of three areas:

Biological-NH4/PH/etc
Environmental- Temp, oxygen
Chemical- Toxins (run carbon)

Things that kill quickly generally fall into one of those three.
