(2 clowns, 2 chromis and a mandarin)

Any info would be of great help!!

If the pod is off the fish there will be holes in the fish and that is what you need to consider QTing the fish alone.
You need to observe all the fish for a while to make sure there are no further isopods.
If there are you may have to leave the tank barren of fish for a while and place the fish in a qt.
