What is this? Flower like thing

[kozik]

Just wondering what these clear flower like things are all over my live rock, are they good? Bad? Neither? 

 

Not the zoa up top but the clear flower thing in the middle of the picture:

 

I have them all over my live rock, since day one... haven't had a problem with them all the livestock seems happy. They are out like he picture normally but when I scrub down the rock they hide.

Aiptasia, they're a pest that will take over your tank. 

Kill them now before they spread.

Aiptasia.

 

Get some aiptasia x, works great.

Turn off pumps/powerhead, blast the aiptasia with the fluid, wait 15mins, turn all equipment back on

I am just wondering if peppermint shrimp eat aptasia? I had a few when my tank was young and they disappeared. I did glue a few down with the coral frag glue .

Yes, they will eat aiptasia. 

However, they can also develop a taste for snacking on corals, especially LPS, once the aiptasia are gone. 

Other methods are safer for aiptasia removal.

Some may eat aiptasia, none of mine ever did but I am one of those many ppl who had peppermints destroy 3 brain corals in 2 days.

 

Aiptasia x is the far safer choice and cheaper in the long run.
