    So i bought a small Xenia tree and it has two stems on it. So ive been really excited and ive had it for about 3 weeks and it looks nothing like the Xenia's that i see at all my LFS's. At the stores they are all flowing and opening and closing, it's just hypnotizing. And then mine just has long arms and just keeps it's hands open and then around 8:30 - 9:00 it just sucks in and goes to sleep. i was wondering if it is just to early, or if im not doing something right. I also have a Kenya tree and it has doubled in size since i've got it. i use and eye dropper to feed them both Kent's Marine ZooPlex once a week.
    Advice will help.
    Thanks.

    What do you have for lighting? What are the tank and what depth is the coral placed at? Also, when do the lights come on? Seems like it is getting photo-saturated maybe. I haven't kept xenia in many years though.

    photo saturated? Never heard of that, but then again I don't have much experience with corals. I would think to put the xenia to the lowest place in your tank; maybe you didn't light acclimate correctly? Also, I assume you have the correct lighting requirements?

    How much flow is it getting? sometime they don't like a lot of flow on them. maybe moving it to a calmer section of your tank?

    make sure your salinity isnt too low. xenia doesnt like salinity on the lower end...what is your tank at?

    my xenia just crashed . looks like i will loss it all. i had had it in my 6 gallon over 8 months ago. moved it to this tank.six months ago, it thrived spread like crazy. was looking sooooo pretty. than bam! crash. left a big empty spot were it was. there is on small sprig left.
    only difference i can think of is i had a heater go bad. and temps were up and down by 5 degrees. one minute cold next warm.
    i did notice after the crash my calcium was low 320. not sure if the crash caused that? or it caused the crash?
    i can say when i was using kalk i seen the xenia take off. so i think cal. plays a part in its happiness.
    a friend who uses purple up has awesome xenia. never a crash in her tank. purple up is calcium based i believe.

    Sorry to hear that. Xenia are know for just crashing out, they did in my tank many years ago. The 5 deg swing shouldn't hurt it, reefs actually commonly swing much more than that very quickly, 15 degrees or so even. I guess if it's acclimated to stability maybe. However, more often crashing xenia is just a sign of good water quality it seems. that would be my guess if everything else is doing well. Seems to need more nutrients than other corals. I've even seen people try to use in in a refugium in place of macro algae LOL.

    For CallMeIshmael I suspect photosaturation because of the consistent timing. This is pretty common actually. IMO, we've gone a bit light crazy and actually, our light can put out a lot more par than what is found on most reefs. Although photo-saturation occurs in nature as well.

    Edit: sorry said photosaturation above, meant photoinhibition... :shame:

    i know its not known why xenia just crash. but do you think the crash could cause my calcium level to drop? i would say the xenias were one third of the corals in my tank, it was taking off ...i had a lot!

    Xenia is a weird coral, and some people keep it for 3 years and then it just dies.

    1.023 is not high, most people say to keep it at 1.025..But 23 is not bad, i would say it is okay right there.

    Post a pic your xenia, maybe it isnt the pulsing type.

    i have LOTS of xenia, more than i care for. much of it pulses, some of it does not. no rhyme or reason to it either, it is a very odd coral.

    I was thinking about this and realize I never responded. I don't have any hypothesis for how death of xenia could drop ca and I can't think of any reason why low ca would kill xenia, or find any references suggesting either of these scenarios could happen. Generally though soft corals are fairly unresponsive to calcium levels, I'd be surprised if 320 was low enough to kill it although anything is possible. IME though some soft corals can be responsive to alkalinity. So, that would be my guess as to why kalk could help. Also, were you dosing kalk when it crashed, that wasn't quite clear. Usually low calcium is either due to lack of dosing or a alkalinity overdose. I could see an alkalinity overdose killing off Xenia. or if your ca dropped, did your alk also drop? Really just guessing though...
