Any Idea how big featherdusters like this get?

[Gigaah]

From the picture you can see there are tons of them. I estimate over 50 on this rock about the size of two softballs. I don't have any idea what type they are or how big they might get they were on some liverock I got.

Usually, the small ones dont get too much bigger. There are different kinds of feathers.

Sorry. Pictures added. They are aprox. 1/4" in size

Those little ones usually stay that size. You may get a couple that grow bigger, but they are called mini feather dusters and they tend to stay that way.

Yes they stay about the size they are now. They come with red feathers and/or white feathers, too.
