rdavidw November 7, 2007 Share November 7, 2007 Part of my Pulsating Xenia has turned yellowish and looks to be dying. Anyone seen this before? I just noticed it today. About a week ago my tank temp dropped down to 73 for a few hours. It typically goes down to 77 at night and up to 79 during the day. I have had the big Xenia for about two months and my other stuff looks ok, except some of my pink coralline has bleached a bit in the last few days. Nitrates = 0 Phosphates = 0 Calcium = 430 Alkalinity = 10 dKH Temp = typically 77-80 PH = 8.2-8.3 Salinity = 1.026 ish 150 gallon glass tank (6) 96Watt Compact Fluorescents 30 gal sump with refugium (5 Link to comment Share on other sites More sharing options...
Rascal November 7, 2007 Share November 7, 2007 IME it just does this from time to time. Sometimes I have cut off the dieing branch(es) out of concern that it would spread, sometimes not. It usually just runs its course with no ill effects on the colony overall. Link to comment Share on other sites More sharing options...

It usually just runs its course with no ill effects on the colony overall. I've had whole (small) colonies die from it - but a separate colony 1" away isn't affected. It's a xenia thing. bob Link to comment Share on other sites More sharing options...
zotzer November 7, 2007 Share November 7, 2007 I had xenia do that too. Every single hand shriveled up, died and fell off. It was just nubs. I moved it a bit, found some detrius trapped under the rock it was on, and it fully recovered. That's my one lone experience with it.

inedukated November 7, 2007 Share November 7, 2007 Ditto. Mine runs out of room to grow (on an isolated island) and it huge chunk of it dies, then repopulates. Ain't nothin but a xenia thing... Link to comment Share on other sites More sharing options...
