Welcome to the forum - sorry it’s under these circumstances.

Post pictures and a video (linked through YouTube). Test params.
Were the fish acting off at all before dying?

Sorry about the circumstance!!

What are your parameters? Any recent changes you made to the tank?

Welcome to R2R and sorry about your circumstances.
Without more information, especially pictures/videos, it is hard to assess what is going on, but this sounds like parasites, possibly Velvet (Amyloodinium), that may have been introduced with new arrivals.

Can you share pictures and let us know tank size, water parameters, type of equipment etc. so the community might help assess the situation?

Something has entered your tank.
2 year old system fish just don’t die like that.
Parasite, viral, bacterial! I don’t know but there not much in the post to move on anything.
Some history, a full tank shot, water chemistry is needed.

If I am reading your post correctly - you had some anemones die. This alone can cause significant problems. Do you have activated carbon running? Also - the implication was that all of your tank died except for shrimp - but - then you mention other fish. Can you post pictures?
