Overnight crash

[berner530]

Hello, so last night I added a banded serpent starfish and a couple mushroom corals (dipped and rinsed) and this morning I woke up this morning and 6 of my fish passed away. I have no ideas what happened I fed last night and added copepods and everyone seemed fine. Then this morning my clownfish pair tomini tang arc eye hawkfish mccuskers wrasse and lawnmower blenny had passed along with my fire shrimp and several of my tiger trochus snails. My watchmen pistol shrimp combo is still alive along with my psychedelic goby, urchin, sand sifting star and new banded star and all of my coral. Fish don’t have anything on them like ich spots but I don’t know what to do now. Water is a bit cloudy and ammonia and nitrite are showing zeros any help or information is greatly appreciated.

Tough to say, but the shrimp also dying does point to something other than a fish disease. Transient low dissolved oxygen levels will cause that.

Can you post a video of the remaining fish?

I’m at work so I can’t get a video now but my watchmen and pistol shrimp are fine non labored breathing and the colors are fine and same goes for the psychedelic. But I can’t provide a video in a couple hours

Did you turn off the equipment to add the fish and corals and forget to turn the equipment back on?

This is not a power outage and agree on low dissolved oxygen. Did you notice prior, loss of appetite or elevated breathing?
With shrimp alive, rules out a water issue however, what is ammonia level and how are you testing it?
