what are these. They have plagued my tank. Will a springer damsel eat these?

Hydroids. Scrape and siphon them out during a WC.

Do you think a springer will eat them? Just did a flatware exit and I'm adding one to my tank to feed on any that remain

 

[NeonRabbit221B]

Not a clue. Never dealt with them personally just know them by shape and research.

New tank?

They typically show up in new tanks, and quickly die out.
