Emperor Angel sudden death

[Coogzreef]

As others have said - Its almost impossible to tell what happened without a clear inciting event. However - if your LFS says that they have a lot of cyanide-caught fish - this would be the right timetable for a sudden death from cyanide. I don't see any obvious problems with your methods.

I’m really thinking this is the cause. I feel like if I asked them they would not tell me the truth about how the fish were caught or tell me they are unsure.

So sorry for your loss.

Cyanide is certainly still a problem in some regions. It varies greatly though, on where the fish were collected. Sometimes the LFS don't know, other times, they know, but say they don't. Here is an article I posted on sourcing marine fishes:

Sorry for your loss as well, that’s rough and I feel for you.

Begin hijack now:

I received my first order from Dr Reef which ended up being a day late due to UPS’s “mechanical difficulties.”

Even though it wasn’t their fault Dr Reef stood by their policy and offered credit for the 3 out of 7 that we lost including shipping. The ones that made it absolutely blow my mind. 2 massive and beautiful Bonded Picasso Storm Clowns, Midas Blenny and super fat Male Lyretail Anthias. They earned my repeat business. To be honest I think the only reason those 4 survived was because of the way they were treated. The ones I lost were 2 delicate wrasses and a lawnmower Blenny. The Lawnmower was alive but died during heated, oxygenated drip acclimation. I think shock played a big part.

I was QTing in my garage and got sick of waiting. Plus as the weather heats up in TX and not having a chiller, limits the months I can QT. I’m going to setup a 300gal and will put in a huge order with Dr Reef when ready.

And that’s why I run an oversized UV.

Drip acclimating delayed shipments takes a bit of extra effort. What happens is the ammonia builds up in the bag to horrendous levels. The pH in the water is low due to carbon dioxide. This reduces the toxicity of the ammonia. However, when you drip acclimate with aeration, that drives the carbon dioxide off, the pH rises and the ammonia becomes fatally toxic. The way you need to treat long haul shipments is to adjust for temperature by floating the bags for 15 minutes or so. Then measure the pH and salinity of the bag water and make up clean seawater that is exactly the same. Move the fish directly over to that (this removes them from the ammonia water). Then, drip acclimate as usual.

Here is an article I wrote on acclimation:

p.s. - great for Dr. Reef to cover shipping losses!
