Colonial Hydroids...

How do I get rid of them? They're all over my zoa rock in my pico. They're ugly and I hate the little feeding web they spit out when I do water changes. I know it's awful but can I glue them shut?

My tank was covered in hydroids before and my mandarin took a liking to them and ate them all lol. Not sure what else you could do to get rid of them, they are a real pain in the ***.

Yeah, definitely. I may look into baby sitting our mandarin from the bigger tank.
