Eagle Eyes shrinking, diminishing...

PWCs? Right now the deterioration seems to have slowed down, I tried dipping in coralRX but nothing apparent fell off. Someone said it might have been astrea stars nipping at them. Who knows what is going on, I'm thinkin increase in macro fauna since I have had my tank fallow and maybe they are hungry as I have been feeding less since there has been no fish to feed.
 
aw crap :/ i just noticed yesterday that one of my blue tubbs polyps looks half brown and is deffinitely swollen..... now im worried. should I do a larger than normal water change? it seems like what others have said?
 
Could this be some sort of chemical warfare? I also see in your picture a skunk cleaner shrimp, I have one also, could it be that?
 
i dont know...could it be seasonal meltdown? It seems to be contagious though...whichever frag that is next to the melting one, will get the similar effect
 
hmm, my point was more that I moved them from their original location. This changed the rate of deterioration so that leads me to believe that it isn't directly on the colonies but rather a factor from somewhere else.

I m thinking possible 3 scenarios

1) asteria stars
2) alkalinity issue i have slightly low, ph is ok, ca is good
3) unknown

I took the one's melting and put them in the middle of the sand bed.... seems to be working a little.

What other corals do you have in the system and are you running carbon? If you have corals which are non compatible - like some types of leather corals, you should be running carbon to remove the harmful chemicals they can release into the water.

Use partial water changes to get your alk in line, then see what happens. If it helps your good, if not, you need to keep looking.
 
I had a similar problem with my long lash eagle eyes. I just moved them and in a few short weeks they came back and multiplied. Perhaps sometimes zoas just need a change of location.

no i had a few different kinds as well. I think it's water params or pest, just can't decide which.

i m more leaning towards the "pest" as I caught a asteria star yesterday on one of the remaining frag zoas i have. i move all the zoas into a frag tank....after I dip them in iodine, peroxide. They seems to recovered.

The water parameter in the frag tank is no better than the main tank....
 
Sometimes too much light is the issue, especially for the people noticing that the mouths are bulging up and the skirts are lowered down. Different zoas/palys can have fairly large differences in light requirements so moving them around to see where they look best is key. When they are wide open with a very slight amount of extension towards the light seems to be when they are happiest.

what if I'm keeping mine under the regular Biocube 10,000k/actinic lighting, middle height toward the light.. and mine are extending their skirts? up toward the light... do you know what that means?
 
I have been keeping zoas for many years and have witnessed similar meltdowns,
some key points:
only a certain species gets affected, zoas open unevenly, some polyps look swollen or inflated, it starts from the colonies edge, polyp towards the edge start shrinking into the mat, then just become totally flat, its more like balding!
i have noticed this happen to my colonies mainly during December to February, no other coral seems to be affected, its more like a seasonal meltdown, the species that regularly melts even on slight change on position or flow is zoanthid sociatus
tubbs and eagle eyes are very close to this species as i have seen them together in the wild! I have also seen similar melt off in the wild populations also...
I have tried every thing from water changes to dips, etc. nothing really helps, one main cause i would say would be decrease in overall nutrients in the water or to clean water, as were these colonies are found in the wild, if u see the area...its so polluted(near sewage outlets) that one would never imagine vast(humongous) stretches of zoas colonies living there!!!

I repeat, during the meltdowns, no other corals suffer, even other types of zoas and palys continue growth, the ones that melt down are ones that stayed healthy for very long but never really grew or spread to other rocks...
So, it seems they were just surviving but not flourishing!

the best way is to frag watever is left, the fragged colonies or the ones that were produced in captivity seldom get into the melting issues...

The above is my observation and i might be wrong, its just that i had easy access to wild colonies around local shores and could get them every year after a meltdown!!!

i have witnessed the melt every January for last three years!!!
