So I have a huge colony of pulsing Xenia and it is in perfect Heath and really full. So I got a frag of blue Xenia. Yes its not anthelia. Well in the past 3 weeks its tripled in size with no pulsing. I looked at it two nights ago and it started getting a really deep blue color then shrunk a little. Then last night it shrunk to almost nothing. My other Xenia looks the best it has in the past 3 months. What do you think happen.? Water parameters are normal. Dripping kalwasser.

Sounds like chemical warfare between corals maybe. Just a guess though. Could be many things going on.

with xenia one day it could be doing great and the next it could be melted and gone for no reason at all
do you run carbon? if so when was the last time you changed it?
with softies and leathers its almost a must, they have the capability of producing allot of toxins to throw into the water

No carbon. Its was about 5 inches away from a 1 foot wide Xenia colony. In a 58 gallon tank. The only thing else near it is some star polyups about 4 inches.

Its the first coral that has died on me in my 4 months of reef keeping. Hopefully its not a trend. I use a canister filter can anyone recommend a good bag carbon to use?
No media in it atm

Rox carbon from bulk reef supply is suppose to be the best, I've heard a lot of good things about Seachem matrix as well. Stay Away from KENT reef carbon! There are many documented accounts of it being contaminated with large amounts of copper. The Petco brand carbon is junk too. I've found eraser sized chunks of iron in it before. I'm not sure but I think its the same thing as the marineland black diamond carbon.

I second the Rox Carbon from BRS. Good stuff. However it is very fine and is designed to run in an upflow canister like the ones BRS sells. With lots of softies you really need to run carbon and lots of it. Those toxins will do a number on other corals...in my experience stony corals are hardest hit.
Another possibility is that the Xenia ran out of a micro-nutrient it needed and the colony collapsed as a result. That is one of the problems with 'weedy' corals like Xenia. They grow like weeds, grow over or into other corals in the process, are prone to collapse, and figuring out why is almost impossible. Reminds me of Caulerpa sp.
Re: other conflicts...give your corals room to grow. The Yellow Scroll and Duncan look like they could be in fighting range in not too much time.

Thank you for the help. Ill give everything some more space and get some carbon going.
