Hey yall. I went to my local reef store and they gave me some free zoas. After having them for a few weeks, I noticed something else was on them. Thought it was 2 different types of zoas. Well now after having them for about a month now, it has started to pop up in other places of the tank and it’s definitely growing faster than my zoas. I’m just not sure what it is. Can someone help me ID what this green one is and if I got lucky with the extra freebies or should I just throw it away. The lights just came on so my zoas are still closed up.
