What is this?

[fisherman08]

This showed up in my tank and I'm not sure what it is

Some type of Xenia.

Are tank friendly???

 

[manbeast]

Photosynthetic, non-aggressive some people like them and some people hate them for how easily and fast they can spread

 

[fisherman08]

Awesome thanks! It came on the live rock that I got from the fish store

 

[manbeast]

How fast it will spread depends on lighting and water condition, it can get out of control easily so just keep an eye on it

 

[fisherman08]

Great thanks

. It's a sift coral very easy to take care of. Can also be invasive

My pulsing xenias are out of control so make sure you have it on a rock they you can easily take out to trim them and frag them.
