Yes. But if the tank has no water, the fish is probably dead and there would be little reason for the bee to waste a sting. So yes, it can; but no it won't.

Should dying fish be removed from the tank prior to death?

Obviously it is best to remove and isolate a fish as soon as you see it is sick if it is the only sick one. Sometimes you will also need to euthanase it. There are a couple of reasons. While it is in the tank it may contaminate others. It is easier and cheaper to treat the water in a smaller tank. It is easier to observe and net a sick fish if it is in a smaller tank.


Should you buy fish with dead ones in the tank?

A basic rule is never to buy a fish from a tank that is suspect or dirty. Buying from a tank with dead fish in is a definite no no. I would not even consider buying anything from a pet shop if they had dead fish in aquariums on display.


If a fish is on the bottom of the tank is it dead?

Not necessarily. If it is sleeping, you can look close and see its gills moving. When a fish sleeps, it also waves its fins just a little. You will also see its mouth opening every once in a while. If you think your fish is dead, DO NOT tap the glass or try to touch it. This will disturb and maybe kill the other fish and the sleeping fish (if it is alive). Just observe the "dead" fish for a couple of hours. If it doesn't move even its gills, go ahead and see what happens if you attempt to remove it with your fish net. If it doesn't do anything you can assume it's dead. Flush or bury it. Do not let it sit in the fish tank once you've found it is dead. It may contaminate the other fish.
