Ok, this one has me stumped.
My newer 55 gallon (8months) has been giving me a few fits, and one of the symptoms has been poor feather duster health. My typical, LFS
vanilla feather dusters I've had in the tank for a couple months constantly lose their heads, and when they do have heads, they are ragged and very small. When I purchased them they were gorgeous.
Tank parameters seem ideal; PH
is at 8.3-8.2 and never fluctuates more. Ammonia, Nitrite and Nitrate are at non measurable quantities. Pink/green/tan coralline algae is going gangbusters in this tank along with Xenia and 'shrooms
. About 60lbs of good LR
and good circulation, but who knows if it's producing enough plankton. Tried adding some marine snow, and target feeding, but no dice. More/less water changes = no effect LFS
guy suggests that too much bio matter in the water can cuase feather dusters to deteriorate in such a way.
I can't move the featherr dusters back to the reef tank because a pair of dwarf angles in there treat them like a salad, and I'm not progessing anywhere with this tank until a supposedly hearty animal like a feather duster can do well.
