Hitchhiker coral? Will they survive?

[Howellfencing]

Hi all. We just started our first saltwater aquarium. It's only 30 gallons and it's been cycling for 3 weeks. We noticed that there were some hitchhiker coral on it and were curious if they would survive. So, will they survive? Should I remove them? Will my cleaner crew eat them when I introduce them? Thanks!

If you got the live rock locally from a vendor you could ask them if they could id the hitch hiker. I would bet they have plenty in their tank.

Some people say xenia is a pest because it can take over a tank, others love it. I have even heard of people putting xenia in their sump to help filter the water. I dont know much about hydroids.
