lost all fish!!

I would suspect an ammonia spike or some other chemical or metabolic cause if multiple fish die at the same time. Maybe test your parameters. To me it is unlikely that an infectious disease would kill everything at once, rather than one fish at a time.

[cuz]

i thought it was all very quick and sudden as well but my ammonia was at 0.1 after having two deceased fish in there till i got home.

I take it you have a corner upright.
Your tank was never suitable for one tang let alone 5. I it obvious that you have a love for tangs but wait until you get a large tank (6 foot to house them)

I doubt ich or velvet killed your fish.

The ich surfaced when the existing fish became even more stressed with the addition of the naso tang
IMO your fish suffocated to death for lack of oxygen f you have ruled out a extremely high heat spike.

[cuz]

how do you figure..lack of oxygen? No heat spike everything stays between 76@night and 78@day. I know having 3 tangs was a no-no and it gets said a bunch but they were all juvies.

Sorry for making a mistake with the number of tangs you have. I mistook 2" for 2.

The reason why I suspect lack of oxygen is that all the fish died quickly.
IME a pathogen like ich will take some time to kill all your fish.

Active fish like tangs are the first to go. You can see a tank which lacks sufficient oxygen
by observing the fish. They stay near the top and sometimes break the surface.

Don't know what causes it but the solution is to immediately place a powerhead near the top of the tank.

Leave the tank fallow for 6 weeks and start again adding fish slowly after you have observed them in a QT
Good Luck

This was the first thing I thought of as well and have experienced the rapid fish losses associated with it.

Cuz, you're not dosing any carbon sources are you (vodka, sugar, vinegar, Prodibio, Zeovit, etc)?

And Naesco please keep chastising people about improper tang husbandry - someone has to ensure more and more ignorance isn't perpetuated on this site.

[cuz]

no, not dosing anything.
so would the lack of oxygen be associated to the ich or say mv infecting the gills?
If done would adding the power head solve anything or just make things easier on the infected fish?

I only see three tangs listed there.... did I miss something?

Do you ever get sick of preaching about Tangs??

lol.. theres always tang police out there somewhere!!
I'm gonna do some reading on mv and see if the signs and symptoms match at all.
