My understanding about BB die off is that it starts to occur once water flow ceases flowing over the filter media. I am sure a large amount of die off occured but I doubt all. If a ray can survive 2 days in a couple of gallons of water during shipping I am sure it would be fine for 24 hours in a large tank. Again I never seen blisters from ammonia burn, just peeling and redness, depending on severity. None killed in that short of period.
Again sorry for your loss but glad the female is doing better.
