Clown Fish Aggressiveness?

HELP!

60 gal tank

My clown fish laid eggs about a week ago and we were getting ready for them to hatch so we turned off some of the pumps for ciculation in the tank (kept protein skimmer and chiller on). We missed their hatching by hours, but now fish are dying (2 day casualties=2 black angels, wrasse, brazilian gramma). Temp, Alk, Amonia, Calcium are at normal levels and the other fish left seem healthy (yellow tail blue damsel and a mandaring goby). Nothing like this has ever happened before. Could it be the clown fish? Or is the turning off of some pumps significant enough to have killed the fish?

How long were they off? Was there any circulation at all? Where is the heater located?

Yes, there was circulation and I think they were only off for about one day.

Was the heater located in the sump? Maybe the temp of the tank cooled and caused some stress issues.

There has been no change in temperature it has been steady.

Well then I have no idea. You don't mention the type of clowns. I have seen some of them get agressive after putting down a nest.

Maybe someone else will chime in with more help...sorry

I really doubt the two events are interrelated...

What species of clownfish?

Thank you for your reponses, I guess I will just have to hope that now that all the pumps are on and back to normal that everyone else will survive.
