Fish die for no reason and look sick? At a loss:(

So my tank is about 5-6 months old 65gallon display 40 gallon sump. My prob is I will add a fish wait two weeks then add a new one then it will die for no reason. I check my water it is prefect water is clear. Corals are happy. And randomly the fish appear sick and dis colored. Then I will do nothing and all will go back to normal any ideas?

 

what are your params?

do you keep buying fish from the same store/tank?

 

Any bullying going on, you have some fish on your signature that definitely have the potential to bully. Is that the complete list of your fish in the sig?

 

That looks like a pretty good load of fish. Listing your params would help. Let us know how you acclimate the new fish.

 

Um I am on my phone so I will have to update when I get to my computer. I put in my stary blennie and the tang was picking at it's fins next day he was dead so maybe it is that.

 

The Acclimation was a long drip but then I was told by a member on here that I should just float the bag and slowly transition the fish in. I am going back to drip Acclimation. I will test tonight and post on here.

 

Make sure and aerate the water if you are doing a long drip. I temp acclimate and then add a 1/4 cup every 5 to 10 minutes until the water level is tripled in the bag. I then carefully pour the fish into a net and add to the tank. All acclimation is done with the lights off and the fish is added to the tank with the lights off for at least an hour after the fish was introduced.

 

I had the same problem before as we'll...I added in a few fish here and thier and lost those same fish in a week or 2...

 

Also, compare the salinity of your tank to the water in the bag. It's important to know this. If they are very close, just do a temperature acclimation.

Why have you decided not to quarantine new fish?

 

Sorry for your lost. I agree need parms, but if bullying is happening have you moved the scaping a bit when added the new fish?
