coral beauty died suddenly can someone tell me what from

[stantheman]

Today I fed my fish mysis coral beauty ate fine noticed it had a weird little twitch two hours later it was dead. Thinking back I have noticed it "yawning" a little occasionally I am dosing with cupramine at a level of .3 for ich. When he died I found him with mouth wide open and white cottony stuff inside (see pics). What could this be?:uhoh2:

Wow pics not uploading not my day I guess.

what size tank and what using for oxygen / surface agitation?

i lost my coral beauty to hlle caused by copper. but what you experienced sounds more like oxygen deprivation if gasping (yawning). or maybe ammonia.

what are you testing your copper with? ---and a side note, you know that .3 won't help with ich, right? need .5

maybe added copper too fast ? angels dont take it well.

 

[stantheman]

Added over 2 weeks I thought .25 would kill ich. Testing with seachem kit and running my skimmer so I am 99.9% positive oxygen not the problem it's a 30 gallon qt ammonia badge says less than .05ppm

 

[Allmost]

havent used any ammonia removers right ?
just FYI. the skimmer would remove the copper if you use cupramine.

 

[stantheman]

No ammonia removers and the skimmer has been running with cupramine the whole time now level hasn't changed at all

.35 is the minimum to kill ich. .5 is recommended over the period.

OK good to know thanks no signs of ice left on this fish either really weird to me

And remember you cannot use ammonia neutralizers with copper.
