Strange Behavior

I added about 20 pounds of rock to my tank 2 days ago. The rock had been curing for a few months in a holding tank by my LFS. Last night I noticed my dwarf flame angel swimming up and down in one corner. He had been living in another set of rocks that hadn't been disturbed. Today I found a banggai cardinal dead. All the other fish are doing fine, including a regal angel and multiple butterflies. I figure they are more delicate and sensitive fish and if they're doing ok, everything should be fine.

Anything to be worried about?

Thanks

Odds are you had ammonia before and now it is nitrite.
