So I have had my feather duster for several months now. A few weeks after I purchased it, the feathers disappeared. Lucky me, I did research that they can drop them and it is probably still alive. Well this time the feathers seamed to shrivel over about maybe 2 weeks and last night they dropped off. I feed it 3 x a week reef roids, spot fed with baster. I only have basic water tests (specific gravity 1.023, PH 8.0, ammonia, Nitrite and Nitrate 0 or not detected by my test kit) Could it be dead this time or just wait again cause it shed feathers and will grow them again?
