Possible Majano and Hydroids ID needed

[Jason L]

I recently setup this tank a week ago. I noticed today what looks to be a Majano Anemone and a small colony of Hydroids; or hopefully some sort of feather duster. I am just looking to get confirmation before I nuke the whole tank and start again.

Thanks for taking the time to help!
