Xenia owners.

They need good light, and stable temp, salinity, and PH.

They don't seem to care much about other parameters.
 
The truth is that nobody knows what xenia likes and doesn't like. Xenia will grow in bad and good water quaility, low and high light. It grows in slow flow and it also grows in extremely high flow. Nobody knows why it struggles in some tanks. Nutrients? Hardly. Light? No way. Flow? Nope. I have xenia that has flourished in extreme cases of each of those scenarios.

xenia is one of the most popular and least understood corals? JMO
 
Perhaps there are variations within the species? Or certain varieties prefer certain conditions, etc...

Are all Zenia created equal?
 
Temp needs to be stable nit too warm. If you does iodine it seems to grow way faster. Some people have problems with keeping xenia that came from nature. Try a peicefrom a RC member or a friend. They usualy live 100% of te time. And I have 0 phosphate 0 nitrate high ca high mag high strontium. I've noticed that most salt brands do not have the right amount of strontium in it. Might want to check yours.
 
I had it flourish (and became a weed) in a 12G nanocube, the very first model that had only 1 24W PC light. I did weekly water changes of about 2G (20%). Sometimes it pulses, sometimes not. Even mother/daughter colonies would pulse/not in the same tank. Pulsing may be because of flow etc, but also may be may be triggered by need to feed.

this is what I ended up with.Never again will I put this stuff in my tank.Water I kept it in was at 1.025 and I never did changes.So,I don't think they need pristine water.And,I was using 4x110w vhos at the time

That did not happen overnight. Xenia is easy to control if you are willing to put the time into the tank.

It does grow fast but not so fast that you can blame the Xenia for the overgrowth.
 
hi everyone, i have my xenia colony for about 7 months now. the past week, it seen like dying out on me. the polyps are not open and slowly melted away. there might be some kind of bacteria infection. my salinity was some how get high last week (1.028-1.029). my ancora and xenia stopped open. i bring the water down to 1.024 within a week span (slowly everyday). now, my xenia is the only melted away. Is there anything that i could use to treat bacteria infection? it is not brown jelly since it has been happen slowly for the past week and i do not any brown jelly over the xenia. they are just melted. Can someone help me out? thanks. it is sad to see a beautiful coral dying.
 
Ive had high nitrates of 20ppm + for a couple months till i got my chaeto growing. My xenia stayed alive and pulsed weak. When nitrates went away they started growing like weeds. I get a new stalk about every week. I have pom poms, silver tiped, and brown xenia. All flourish and like to be as high up in the tank as possible with very low flow. I even have some in high flow and do ok, just dont open up as big. They sit right under 250w 20k radiums and t5ho's. I dont know why some people say they like tanks a little dirty. My friend and i keep things zero across the board and they pulse as fast as they can and grow so fast its crazy. Ive read they benefit from iodine but i only supplement that every 3 weeks or so because i dont test for it.

My perameters have always been dead on. I had on head in my tank about 2.5 yrs. When I changed from pc lights to metal halide that is when it all changed. The xenia started to pulse like crazY and started to split like no tomorrow. Within 3 months my single head grew to 30. Now I must prune about 30 heads every other month. Don't get me wrong. They are a beautiful coral but they can tend to grow to plague proportions. When I set up another tank (hopefully this year) xenia will not be a part of it. I feel that their growth deffinitly has much more to do with light quality then water perams. Just my opinion.

i dosed with Reef Builder a week ago and also added it to my top off water. at the time, my alk and pH were low and my xenia were not doing so well, especially after fragging a few heads. 2 days after dosing, all xenia are well open, looking good and attaching well to frag disks, but some are not yet pulsing. i have been adding iodine every few days and and checking on them from time to time. they'll be heading to my lfs when i get back. df
 
I've had xenia for over 2 years, started with a couple of small stalks, and now its taken over my tank. I have to disagree with having perfect water quality. For awhile, I wasn't on top of my tank maintenance and water changes and it grew even bigger. I don't understand it, but I have given it to friends and none of them have been able to keep it alive. One thing I know though is, they need to be supplemented with iodine, they love it. I would say some of my stalks are easily over 5-6 inches long.
 
I have had xenia growing in my tank for about a month and its doing well. Mine is in an area with relatively little flow however I have seen it grown successfully in much higher flow rates.

Tank Parameters:
Salinity- 1.022
Temp- 79
Nitrate- 20
Nitrite- 0
Phosphate- .5
Calcium- 500
Lighting is approximately 2 watts per gallon
 
My water parameters are

Ammonia 0
PH 8.4
Nitrites 0
Nitrates <5

I have coralife T5HOs for lighting.

My xenia seems to be doing well - it pulses and has split once. I placed it high in the tank and not touching the glass to (hopefully) avoid a takeover.

Here is a pic:

I could never keep Xenia successfully until I installed a chiller - big temps swings and especially high temps are a killer. The stuff that is regularly fragged around between my mates thrives in a variety of tanks, under widely varying conditions - temperature control seems to be the most important variable.

cheers
