Is it weird that...

GSP should be open in a day.
But the one on the right looks a little light colored.
If it dies, I have tons more - free. I have to prune it regularly.

Be warned on GSP : It will take over!!
Give it a dedicated rock. One plus though : It really only grows up and sideways, not down.
So if you put it on top of a pillar, you are fine.

Oh yeah, the GSP did already start opening up. And thanks, I will keep it on a dedicated rock.

I posted this on my tank journal, but I'm hoping for a quick reply so will post here to. I found this little guy, must have hitchhiked his way into my QT on that chunk of rock I put in yesterday. Anyway, it looks like a tiny starfish. Are they safe? And if so, what should I feed it?

those guys are ok, consider it part of your clean up crew and they multiply

 

[DeeAnnMG]

OOOO, really? It's in the QT right now. Should I try and move it to the DT?

It is an asterina
On the glass, they are fine. But if you see many of them on a coral for an extended amount of time, they are bothering if not eating it.

Thanks you guys. I did find a bit more info on these little asterina, and as usual you're absolutely right. This little guy (we call him Tortilla) is still alive, but not traveling around the tank as fast as the first night. I hope he's okay.

Careful with zoas and palys. Poison! For real. Goggles and gloves. Best to do what you're gonna to that rock under water so they can't spit at you.

Some are known to eat Montipora... so if you value Montis....

As I read more about them I'm getting mixed info. It seems like at lower numbers they're great cleaners. But as the number of them reaches some (IDK) critical mass (?) they start attacking coral. I think I'll just leave little Tortilla in the QT for now.

Asterinas can reach plague proportions if left unchecked....be careful.

There are also different species of Astrina that people simply call Astrina. While one may be good, another may not be. I'm no echinoderm expert so do not ask me.
