Tangs died!

[Arthur9.5]

The last monday, I stick with polyplab premium glue the majority of my corals, around 12 frags. I keep some softies frags in the sand.

In thursday 19, I glue 2 new frags.

1 day later my blue hippo tang (2 weeks old with me)started to breath fastly and doesnt move too much and I decides to take out to prevent to hurt my tank and corals

in sunday my tomini tang die too with the same features.. the tomini was in my tank for 2 months.
I do 2 25% water changes in one week to lower parameters.. my nitrate kit is expired but the result was 10.. I know too high. Today nitrate is in 5.
Any comments on this?

Nitrates under 100 wouldnt have done that to healthy fish. Could something have been in the glue, dont know, more likely something between the frags/glue/messing about the tank and with them being newer fish? Was the hippo in qt before your display or you've had him a total of 2 weeks?

Your fish may have a parasitic infection. Did you QT your fish? Did you see any changes to their body before they died? Expired test kits can yield inaccurate data, but fish are rarely bothered by nitrates under 50. Do you test ammonia? Can you tell us in detail when and how this system was setup and how you went about adding fish?

Definitly sounds like an infection. The corals would be more sensitive to water condition changes then the fish.

You mean that if thats a infecion the corals could died first?

And no, unfortunately i have never qt my fish.. just dip some corals. I dont have additional space in the room for a qt tank

What they are saying is, if it was the water you would notice a decline in your corals. Therefore, it is more likely an infection in the fish.

Did you glue 12 frags in one day and 3 days later glue 19? Am I understanding? I'm sorry for your losses

I'm also wondering how old your tank is. Introducing several new corals and the fish being in 2 weeks.
