sick Flame Angel?

[BadKharma1]

This morning my gorgeous Flame Angel seemed peachy, tonight I get home from work and shes not ok. Lying on her side. All my water specs are within parameters. my livestock list follows.

1 Algae Eating Blenny
5 Blue/Green Chromis
1 Koran Angel
1 yellow Eyed Bristleback Tang
1 Flame Angel (the sick one)
1 Peppermint Banded Shrimp
Various Snails of all sorts
55 Pounds of LR

55 Gallon tank

Im doubting shell make it thru the night and wondering what I did wrong or if its a Livestock issue. The tang sometimes seems a little aggressive and I think he may have harrassed her to not eating. Not sure and shes such a beauty id hate to loose her. Any ideas, comments, advice?

:(

Are you sure it's the tang? 55 is tight for all those fish, esp. 2 angels (the Koran and the flame). I'd thought they must certainly would have fought by now?

Tank is def. too small for the tang and the koran. Those two fish and the flame all need space to sort of stake out their territory. The tank is just not big enough.

Any signs of disease on the flame or any other fish? Double check your params (maybe take a sample to your LFS), and do a water change. That's all you can do at this point.

If there are no signs of disease and your params really are ALL within normal, then I would probably blame the koran and the tang.

Your tank is to small for all of those fish. The Koran needs at least a 100g tank. I have a 90g and wouldn't chance having 2 angels.
I would blame the Tang or the Koran for your Flame's condition.
