What do you think this is?

These volcano looking creatures came in on a zoanthid piece I purchased from LiveAquaria. I hope they are not bad...

Kind of looks like a tubastrea/sun coral head

There's also a little aiptasia next to it

 

[Teague75]

Those aiptasia are a royal PITA. I have purchased 6 peppermint shrimp and they all have disappeared overnight. I have been using Aiptasia X to try and control it, but they keep popping up. I wish I new why the peppermint shrimp disappear.

 

[Darkxerox]

Got any wrasses or other predators that might be eating the shrimp?

 

[Teague75]

Nope, no wrasses. I have hermit crabs. Maybe they are eating them??

They are really good at hiding when first get them

 

[JVU]

Might be barnacles, maybe dead? Anything ever come out?

I see a sea squirting the left bottom quadrants
At 2:30 from the squirt is see the tentacles of an aiptasia

 

[Teague75]

They open and close when a fish swims buy.

Whoops
The squirt is the center of the picture
There are 2 openings for water to flow through
It’s a filter feeder
It’s very cool!

What are the zoas?

 

[Flagg37]

Definitely an alien species.

The shrimp could be hiding out in your rock. I have sworn mine were gone, only to see them swaying upside down in rocky caves and coming out to take bits of fish when I fed the tank.

 

[Teague75]

I am not sure what the zoas are called. I purchased them to get my tank started.
I would love it if those dang shrimp made an appearance. I looked last night around 11:00 p.m. with the red flashlight. Did not see anything....

Yup, definitely a tunicate. Feeding phytoplankton and bacteria products will help it survive. It won't harm anything, and for me, very desirable.

Unbelievable. Last night around 11:00 p.m. I was looking at the my tank with the red light and I actually saw one of the peppermint shrimp. I thought all six I put in there disappeared. Then it went into hiding. I wonder if the other 5 are sill in there?

Not unusual ime. They hide well and are active at night mostly
