i got mine from the lfs
for free becasue they were almost dead. they just could not keep any xenia a live in there tanks. they tryed every thing to make them grow. but nay way they gave it to me becasue i was asking them to order it for me. but he said there has to be a chemincal in the water for them to do really well. he did not know what it was and i dont think any one dose, but some tanks have it some donot. minemust becasue i brought them back from the dead. you you might want ot do a large water change or some thing and see if that replaces the chemical they need. just a thought

bow front (Soft coral) reef tank with a 10 gal
sump. And a 30 gal
