Get home form work, my fish are dead / dying...

No I don't think that would have done it. I really think the shock of acclimation and moving was what did them in. Does your LFS have a guarantee? You might want to freeze them till you can get back to the lfs or take them back now. I'd hold off on the water change for a day or two and see if the remaining one makes it. I think a water change now would only stress it more

 

No, my LFS offers no guarantee or returns on SW fish or corals...They give a 48 hour one for FW i think though....Ok, thank you so much for your help in this! We'll see how she does, hope she makes it.

 

freeze the live fish?!

 

UPDATE: Looks like lil' blue is gonna make it! She has not been hiding in the LR, she's eating now, and her color is staying good....Normal breathing as well. Thanks again for all your help and input guys!

 

propper salinaty is 1.025-1.026. i run mine at 1.026..........1.021 or 1.022 is to low IMO they are suffacating. but bringing your salt up should be done over time not all at once.

 

I would think it was the acclimation if you did not drip or dunk since you did not have a problem with the mushrooms and the feather dusters. I think the domino is the more fragile of the damsels until they are acclimated and established. Just my .02
