Fish found dead after fragging zoa

[Matt1]

I have a 55 gallon internal hydro skimmer
And hob filter soft coral with life rock.
Last night I fragged a zoa that was attached
To two rocks two split it. I did this inside the tank.
This morning the yellow I tang was dead,
And the Orchid dotty back was almost he died will
Getting water ready for a change.

The remaining fish is a pair of clowns and a pink spotted goby.
After I woke up I performed a 25% water, and changed Carbon.

Parameters before water change was,
Ammonia =0
Nitrite=0
Nitrate=0
PH=8.1
Reef tank is 9 months old, the Orchid was put in
After tank cycled. The Tang was put in one month ago.
I used the marine epoxy that you get at the fish store and crazy glue.

I'm not an expert but zoanthids can contain an extremely powerful toxin. You should check out http://www.reefcentral.com/forums/showthread.php?t=1966900

Probobly just coencidence but you shouldn't have kept the yellow tang in a 55

YEllow tang does take a 100* gallon tank. The others are fine in that size.

Whenever soft coral is disturbed in any way, run a sack of carbon in your water flow: it absorbs some of the coral spit, which is unpleasant at best and toxic at very worst. WHen any coral is wounded, it is a good idea.

Generally remove the coral from your tank to frag, and disposed of any water involved in that operation: don't permit dogs or cats to access the water, either. Rinse utensils and nets, and restore coral to the tank with carbon running. HOpe that helps.

zoas? makes me think palytoxin.

if you're not familiar with palytoxin in some z's and p's, you should check it out. nasty stuff.

the main reason i got rid of every zoa and paly in my tank and no longer keep them.

Thanks for the advice, I'm guessing it was the toxins that killed the yellow eyed Kole tang.
I was aware that it was harmful, I did wear gloves and glasses. I just have never heard of it killing fish.
Kinda sucks liked the Kole tang will get another in the future. And will frag in a separate container with caution.
