This next pic below,these look alot like what Ive seen others describe as bite marks? From my reading if it is something like AEFW arent they only suppose to affect acropora and not birdsnest?

Fish Include
2 ocellaris clowns
2 helfrichi firefish
1 C. argi.(pygmy angel)
1 Heptus tang (blue hippo)
1 pistol & goby pair ,completely sand dwelling
1 red serpent star

I have seen only on rare occasions asterina stars,I ve never seen them in or around this coral.I work nights alot so at times Im able to the tank in the wee hrs of dark and haven't seen anything bothering it.I will keep a more close eye out though if you suspect
it maybe the issue.

SPS corals ,I dont have many.I have 2 acros both growing extremely well,a few caps ,setosa growing well.bird of paradise ,whitch I think is a birdsnest is also growning and well colored.
I have the issue with (as noted in this thread golden birdsnest) and another the ponape birdsnest.(i.e.- poor polyp expansion and very poor color and doesn't seam to be growing at all.

In all honesty my sps experience is very limited,if you even want to call it experience.The first "mature" reef I ever saw in person was cullys back in sept when he was breaking it down.Caught in a foreign place when it comes to sps.Much to learn yet.

Is it possible anything near by has sweeper tentacles?

To my knowledge, AEFW would not affect seriatopora hystrix. Another type of FW, I don't know. It certainly is curious. I've seen certain corals stress out due to sub-par or unstable parameters, but those pictures don't look that way. It looks like single polyps have been sucked right out of the skeleton.

Any suspect crabs?

As far as birdsnest's are concerned, I've found them to be tempermental. That's just me, generally they're supposed to be pretty tolerant corals.

I can not agree more,I have many different kinds of sps that are thriving including my tyree ponape birdsnest, but those types of birdnest corals are killing me..I had one the size of a softball,I fragged a small piece for someone(just a small frag) and the whole damn colony died on me.. :mad2:

It's dead skeleton does make a pretty cool knicknack though..:blown:
 
I don't know what those splotches are. Asterina could be irritating or eating a little. Perhaps the serpent is irritating it.Acro eating flatworms , only eat acros as far as I know. Maybe your centropyge argi thinks it's a soft coral. Anecdotally Melev once told me his seriatopora was a harbinger for high nitrate problems. A few years ago when my nitrates built up they were the first to struggle.
 
I can rule out sweepers by another coral.Nothing close by.

Crabs -most died from an interceptor treatment.Have a few but they really dont seam to be bothering anything.

I have 3 clams and a few softies whitch the pygmy angel has never bothered ,he seams to stay interested in picking little bugs off the glass and rock.

Serpent star I dont think could be it either.It stays in a cave for the most part thats in the far left area of the tank,even at night it doesn't come out very often.The birdsnest seams fragile and I was thinking if it were the serpent Id be seeing some fragmentation.Nothing noticed.

I cant rule out .
Asterina stars-but honestly I have seen very few in my tank.
Some kind of flatworm or bug
Instability,maybe but the only issue I had was salinty and that was far enough back to where I dont think it should still be a likely cause .About 6 weeks ago since correcting.

Elemental-that could be.I should probably just buy a nitrate kit and test it.Though I cannot grow chaetomorpha nor caulerpa.I get some turf algae like bryopsis but its minimal at best.Probably not the best approach I know but I just use some basic observation.Glass panes in DT get light dustings and not much more than that.

Testkits I have I will post up with parameters shortly.
Thanks for the insights.
 
Yeah, from my inexperienced eye this looks like someone is havign a second lunch. polyps getting pulled out - I'd suspect the angel as well.
 
If you guys think the pygmy angel is alikely candidate,I could move the colony to the left side of the tank.My clownfish dont like the angel and they make it clear to him where hes not allowed to swim. I think it would rule out the angel as a cause.
My gut feeling though is the pygmy is'nt to blame.I 'll try it though.
 
Yep, I gota ya. Not ruling him out yet .Im going to move the birdnest to the other side of the tank.My clownfish are real strict with the angel coming into their turf.
Appreaciate you throwing the link up ,too.-Steve
 
Tds ~0
Refractometer 35ppt (I do not trust this thing so I recalibrate it everytime I use it now
Mg~ 1470 ppm (salifert)
Ca~ 480 ppm (salifert)
KH~8-8.3dkh (salifert)
Ph~ ranges 7.8-9 to high of 8.33 on an average 24hr swing.
Temp 78.5

Stuff above stays consistient through a controller,waterchanges and a steady trickle of limewater from a 60 gal bucket mixed or just restirred about every 3 weeks.

I have to pickup a nitrate kit later today.
 
Picked up a nitrate kit about an hour ago and just tested.
I used the medium range per the salifert kit.

No3 is reading between 0-2 ppm.Id have to use the low range to get more accurate than that.Still ,it does seam its in the exceptable range.
 
Took some pics whitch show what I was thinking might be some kinda eggs.After clipping all the color and zooming in.It shows a single polyps that appear to blister.I'm pretty sure now that at some point the blister peels off the skeleton.Giving the impression its bite marks.

Ive been watching the blistered areas for a few days now nothing new as far as bite marks or new blistered polyps.

Starting to think this started with from drifting refractometer even though it was around 6 weeks ago when I noticed it was at 1.021 .Guessing it just took some time for those small blistered areas to peel away.Anyway,heres the pics of what I thought might be eggs or something.

Trying Gary. I'm not real computer savvy , just started to learn /use Raw software.I use the free versions.

I spent over 3 hrs on the last 2 pics. Ill try again though.

FWIW- I must have misread Ca test. Came in at 400ppm last night and today.The other par. were right though. (salifert has .02 and 0,2 on the syringe ,think thats how I misread it.
