A dead clown. What happened?

I bought 6 fishes from saltwaterfish.com. The 5 are still alive, look well, but one clown died today. The other one is swimming happily about around one side of the tank.

I did notice that the clown that died has very rapid breathing. In fact, both clowns were breathing rapidly on the first day, but it calmed. On the first day, the "sick" one stayed at the bottom of the sand, upright. He didnt move much and I was very worried about the rapid gill action. It did not go away on the 2nd day, but the two were swimming around the tank so I brushed it off.

Was improper acclimation the cause? (I just read that floating too long causes ammonia spike when exposed to air) Also, the water the clowns were in had a green tint, my guess something added to help surviving the trip. I did the cup method, adding 1/8 cup water every 15 min. Their SG was at 30 ppt (about 1.020) so it was a very gradual climb to 1.023. (total acclimation 1.5 hrs)

I am using a 55 gal as my QT, it has sand LR and filters, etc. Basically a normal FOWLR tank. All readings are 0 (its an old established tank from a friend, but I did a fishless "re-cycle" for 2 months anyways) and I set SG at 33 ppt (about 1.023). I use an electronic meter instead of refractos.

As far as eating, neither has been eating yet. Im thinking could the environment be too big for them so they are scared? They are 1" juvies. They are going into a 125 once QTed.

Trying to understand what I did wrong, I feel like a fish murderer.
 
Since you had a QT setup, you could have matched salinity and just dropped them after acclimating to the tank's temp by floating the bag.

Sometimes fish don't survive shipping well, but the rapid breathing is worrisome. There could be ich or flukes in gills. Watch them carefully, and try to eliminate stress in their world. The treatment is different for each pest. You might go to Fish Disease forum in RC and see if symptoms add up. If breathing has normalized, I'd tend to call it shipping stress and just go ahead with TTM or whatever protocol you have decided on. Ammonia would have affected ALL of them given same bag or same conditions, though it would have affected the weakest worst. I don't think that's the cause in this instance.
 
Thanks. So the other clown is doing better, Doesnt seem to breathe as rapidly anymore, although still fast compared to my goby. He is small (< 1") and he blown around by the powerheads. Could it be too strong? Hes swimming around and eating. It could be i did a bad acclimation job. No other fish died so far so could be he was weaker then the rest.
 
Blown about is not a problem: these fish live in tides in the wild and often end up pushed and pulled about. The question is whether he's swimming strongly or going end over nose. The current in my tank will give a workout to a nearly 5" stout damsel. My 1-inchers just ride it into the shadow of a rock to make progress. If the fish is eating, good.
 
If your QTing them then I would suggest putting a wide range treatment in the tank to eliminate any possible diseases, turning off any lighting and adding a mirror to the side of the tank to further calm your fish. Check all water parameters are good. A lower salinity will also reduce stress, take it down to about 1.021 for a few days. Try to also not put your hand in the tank or interefere with their environment in any way.

Best of luck

I recently ordered a large shipment from saltwaterfish.com. 3 of them were fish. I still have the Royal Gramma and it is doing well. the mandarin and tailspot blenny died within hours. The corals are doing very well. IMO order corals from them and not fish. The water was yellow for the fish before I started acclimating them and I don't know what chemicals they used.
 
It might just be my experience but the mirror worked for my clowns and tangs and especially butterflies. It might also help the remaining clown as he could see his 'potential mate' in the mirror.
 
I suspect that the clown had something already, but the one thing I see that you mentioned is that this tank has been fishless for two months. Even with live rock, the bacteria may have died back to the point that adding six fish all at once could be problematic.
