So I started noticing these things on my top rock, closest to the light. They have been growing a little bit every day, and there are about 10 of them. Can someone please help ID these for me? Are they good? Bad? Thanks!

It's a harmless type of plant can't remember the name.

Scroll algae?

Halimeda? Does it look like this?

My guess ^

It looks simular..the shape of the top of the "money plant" looks the same. The color of mine is like a dull yellow. Maybe if grown larger I can see it turning into this. Not sure though...

Im debating if I should cut them down, there taking up the spot im reserving for SPS

I'm revoking my earlier question mark. Seriously, google scroll algae. Same shape, same color, slightly transparent.

I had some for a bit and it kind of got shredded when I pointed a koralia at it.

Moderately fast grower, not difficult to control if you decide you don't want it.

Yea that is exactly what it is...My Koralia is pointed at them right now..

If they start getting too big ill just rip them out I think..
Think they feed on Nitrates?
