Some Softies wilting

[ianward]

I have a 160 (total) Gal system with 100 Gal display and have had all kinds of softies, Zoos, Branching Hammer, Gorgonia and a few Acros.
Fish are a Bicolored Rabbit, Hippo, Flame Angel, Firefish, Mandarin, and assorted Gobies.
In just the last 3 weeks my Zenia had shriveled up to almost nothing and my Yellow polyps are shrinking and not been open either, also one of 8 different Zoos have all but vanished.
I do have some Flatworms (which have bugged the Hammers), (but the new Mandarin seems to be eating them) and I did 2 Red Bug Treatment treatments (interceptor).
My water parameters are all Ok.
Any ideas why these two softies and one Zoo, suposedly "easy corals" would start to melt?
Thanks
Ian Ward

1st thought - Flame angel eating them?
2nd thought - is it time to replace the light bulbs?

Well I havn't seen the Flame Angel eating them, but he does peck at a few Zoo's from time to time.
Lights are about 9 months old, it's a Coralife Aqualight pro 24" 250W.
