Quarantining w/rabbit fish

[billw]

I recently lost a Genicanthus Lamark while treating with chloroquine in a 20 gallon tank with a foxface. The day before the angel was eating energetically with no symptoms. The next morning it was dead. This occurred a week into treatment so i'm reasonably confident that the angel was dealing with the chloroquine well. I noticed that they hung out close together most of the time. My only guess is that the angel got stung and succumbed. Note that there wasn't a trace of ammonia and the foxface is still doing fine a week later without need for a water change (I'm sure people will ask ). Comments, please?

Did you happen to notice a protrusion near the swim bladder area? A number of Genicanthus are not being properly decompressed upon collection and as a result, gas bubbles are forming in their swim bladder. Sometimes the gas bubble is large enough to see, sometimes not. A LFS I advise had 4 Genicanthus "drop dead" in a week's time (no medication was in their water); a necropsy of the last two revealed small gas bubbles in their swim bladder.

I recently lost a purple tang in QT with a foxface. Over 3 weeks into CP treatment, was eating like a pig and then stopped one day and died 1-2 days later. No visible signs of any issues. They hung out close together at night and sometimes during the day so I was thinking maybe it got stung as well.

I didn't notice anything unusual, but I could have missed it. Were there any symptoms while they were alive?

Nope, they just drop dead unexpectedly...

I shouldn't have too many more opportunities to quarantine Rabbit Fish so I think I'll quarantine them in isolation and be careful in the selection of my source of Genicanthus in the future. Thanks for the input guys!
