I agree that this is a tough subject to address. Some noted authors and hobbyists suggest that depletion of iodine causes crashes, but then there are others who never add iodine in any form and still have good Xenia Growth. Divers have noticed Xenia colonies will die off naturally then grow back. Some swear that high temps kills Xenia off in short order. Predation is also a possibility (some crustaceans and fish eat Xenia). I'm sure there's more possible explanations I missed.
It's really hard to say why you haven't been successful.
I do know that high temps kills xenia. Just a few days ago my state of the art electronic titianium heater when crazy and by the time I noticed it, it was reading 100.7 F...killed my xenia and my newly prized Finespotted Fairy Wrasse..ofcourse all my cheap fish lived..go figure.
How is your xenia dying. Is it turning to mush, is the carpet receeding? I had some that was the carpet type. For no reason it started receeding, all the arms completely dissapeared and what was once the size of a half dollar turned into smaller than a dime. But it never totally disapeared and today it has grown back and is getting back to its original size before the receede.
Mine grew like weeds and crashed overnight. I've heard of this happening to many reefers for no aparant reason. I love xenias but have never been able to keep them long term. Have tried about 3 times already and always start well for a few months then they die. No change in parameters, temps, ect. Go figure !
When you all figure it out, let me know. I've been stumped over this for the last 3 years. I can't get the stuff to grow or stay alive and I've tried it all. :roll:
Tongs fish store in socal has some in their main display tank that the main stalks are as thick as my wrist...appears as if they have figured it out..maybe i should give them a call.
hi.
Just because someone has the Xenia doing very well in the tank, it does not mean that they will be able to help anyone else. Just look at me. I got the stuff growing like mad, and I won't put my money on it if you take any of my Xenia and follow everything I do.
The xenia I have in my tank is bullet-proof. I swear I couildn't kill it if I tried. It's probably 10th generation captive bred. If anyone in my area wants some, let me know and I'll happily give you some frags. I'd be interested to know if maybe some xenia are harder to keep than others.
_________________ ways to save money
true..but I would see no harm in trying what another person is doing..esp since it is obvious that the current way is not working out..so whats the harm.
hi.
I never talk to Tong's people on Xenia in particular, but be forewarned that they may come up with thing like feeding and additives (e.g. Iodine) that you need to buy, etc.
Some Xenia are more demanding than the other. IME, regular IndoPacific Xenia (X. elongata) is the easiest and cheapest and most available.
I always seem to see Xenia thriving in relatively nutrient rich water with moderate lighting and current. I can't get it to grow in a really nutrient poor tank - especially with a lot of circulation and very high light levels...
Of course now someone will chime in with the opposite observation...
Seems to be a hit-or-miss species for whatever reasons...
