Feather dusters?

[Wayne P.]

Good evening all. Just got my tank moved into my new place. All settled in and I noticed what I thought was a feather duster. Then I noticed a multitude more. Any ideas? And if they are bad, how do I get rid of them?

If it goes in and out it's a feather if it stays as is and does not react to anything...then sponge

Pineapple Sponges -

Very common good hitchhiker. These little guys are a type of sponge. They are most commonly found in overflows and in high flow areas of the sump. However, they can sometimes bee seen in shaded areas of your rockwork.
