Feather duster placement

[Teufel72]

I have a feather duster that was doing very good. But my Diamond goby keep digging him up and the worm is now not doing soo good. À tried Changing his placement but the Diamond do is duty on cleaning the sand every where very Well. Any idea 9n what I could do to help my duster?

Try putting it in the rock work. It'll attach and hopefully the diamond goby will leave it alone
