How long have you got those fish? because they could also be infected with some parasites, thus the fast breathing.

At first I thought you had those fish for a while but it seem not that you added some fish recently? since the wrasse was the one who died, when was it added?

If your fish are not looking better and they are breathing fast, they could have some disease or parasite. YOu may have to treat those fish. What was the wrasse looking like when it died? was it sort of whitish or with a film on it? did it have any white dots?

I think in your case it is either something in the water from the tap water or a disease/parasites. The first one is easy to cure with carbon and water change but the second will need a treatment.

If all your fish die from a parasite, you will need to leave the tank without fish for 2 months minimum, or else every new fish is going to be contaminated as well.
