Help with unknown algae

christiantt · Jan 28, 2017

I've searched the internet and looked through all my saltwater books, but I can't find an answer.
Anyone here who knows what algae this is, and how to get rid of it??
I've tried to remove it manually, but it just keeps coming back :-/

I don't think is an algae but an hydrozoa myrionema
But @Tahoe61 could help you

Spot on bios. Thanks :-)
But it looks like I have a small war coming :D
Maybe it's time for change in the tank :rolleyes:

Definitely not an algae and I agree with bios ID.
Thankfully never had them in my tank.
Being that they appear to have taken hold, the cover with epoxy method is not going to work. Finding the animal that eats them will be very difficult, I imagine they are on some specific nudibranch lunch menu.
The link below should be of assist.
