feather dusters; feathers

[Maxi]

My feather duster decided to let its crown fall about a week ago. Yestarday, I saw an inch big crown growing back.

I'm wondering, what do I feed it to help it out? Its been in my tank about a year and I never feed it anything. This is the first time the crown dropped.

they are filter feeders--no need to suplement. Just make sure they have some flow around them and they are not surrounded by rock so that some of the water flow goes by them.

However if you are not feeding other critters mysis and meatfoods then:
daily to a few times weekly offering of live (brine shrimp nauplii, rotifers...) Use a turkey baster to squirt the food around them and turn off power heads while they are feeding
