Fish Dying: Breeding Clown Fish Aggressiveness?

[dbernal]

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?

my fish breed all the time and I have not had this before. I have heard in tanks under 100gallons there is some bacterial issues but only heard it killing the babies not other fish. should not be pumps being shut off. I do use an airstone in the tank for oxygen when its off a long period of time

Thank you for your replies. I will just have to wait and see what happens after all the pumps are now back to normal. Hopefully there will be no more casualties.

shutting off the pumps will cause yoru oxygen levels to drop so fast is not even funny, so that could be a cause of it.
