Queen angel died

[tcarter1936]

I can't seem to figure it out, I came home to find my 6" queen angel dead, I'm not getting how it happened. Had her 5 months now and even yesterday was fully active and eating like a pig.
Nitrate 5
Amonia 0
My kole tang is doing excellent
Only thing I did yesterday was move a 60+ lb rock about 6"
Hopefully didn't stir up something. Tank has only been running 8 months and has 2 " sand bed

Some people believe hydrogen sulfide develops in area where oxygen is low . ( under rock) Moving rock could release and cause poison. There are so many other possibilities it is impossible to know?
I had a large fish grab a whole nori sheet swallow it , and expire later that day. I thought he might have choked. Again , not sure if that is possible.
A 60 pound rock is a beast.

Thanks here's a better pic it would never stay still for a good pic lol

I'm so sorry.

I'm so sorry.

Thanks it's surprising how attached you can get to a fish. I also know that queen angels can be hard to keep however I'm always surprised to lose a fish it so rarely happens to my fish. I do plenty of water changes and keep my tanks pretty clean. The new build and the move/ remodel had convinced me to hold off on purchases until my fowler is up. NowI'm going to shut down my qt until right before I'm ready

Getting attached means you care enough to do the right thing for them. We are so privileged to get to keep a piece of the ocean in our homes.

It seems to be related to moving the rock, whether it an anaerobic zone being distubed, a cryptic parasite, or it was stressful or shocking to the fish.

Is that a cement rock?

 

[tcarter1936]

The smaller one in the middle is the only man made rock,but it's been cycled and been used in two different systems without incident. The large one on the right has been used by me for two years then dried and acid dipped and been in my current display for over five months

 

[tcarter1936]

Also the one on the right that has been moved around is real rock

All it takes is one broken chunk to exspose very high alkalinty to the water.

Id test your ph and alkalinty.

Personally I wouldn't use cement rocks. Too many chemicals and risks.

 

[tcarter1936]

Good point I'll test

 

[tcarter1936]

Salifert 8.3 dkh
8.0 ph

I read an article recently that, despite being illegal, many saltwater fish are still caught with cyanide. I don't know how long it would take for the effects to show if that was the case, but I thought I would mention it.

If it's the article I'm thinking of it was mostly outdated info from way back and the rest was just made up.

 

[tcarter1936]

Thanks but I've thought about that however my lfs had her 7 months and us at least 5. So I thinks it would be an unlikely cause.

 

[tcarter1936]

I've also hard of cases of ich were it's only on the gills but this fish was biting at my fingers to eat the night before and no weird behavior
