what are these?

[frankness]

found these on a small piece of LR. what are they?

 

[snakeblitz33]

Hard to tell from the pic. Look up "mojano anemone" and then look up "brown button polyps" and compare them.

 

[frankness]

They are so small its hard for me to tell, looks like it could be either one. Should I let them get a little larger ?

 

[meowzer]

Touch one.....if it is a majano (or pest anemone) it will retract totally....if it is a polyp, it will only close partially

 

[snakeblitz33]

Not sure if you should kill em or let them grow. I personally err on the side of caution.

 

[frankness]

I touched them and they didnt close all the way up but I think I will get rid of them anyway.....

They look like Zoanthids to me. I suggest keeping them until they have a chance to regrow Zooxanthellae.

I also found these today! any ideas

 

[snakeblitz33]

can you describe their nature? do the ends open and close or do they just sway around?
It could be anthellia. It's a pretty cool little coral, but will grow very fast and spread wildly.

They seemed to close a bit when I touched them, they dont blow around much . There is about 20 of them on a 4 lb piece of LR .

 

[frankness]

While I was just looking at them I noticed another creature! It opens and closes......

 

[frankness]

They disappear when the lights go out , retracting back inside of a tube.

The feathery polyp things look to me like Anthellia or an encrusting Gorgonia. Time will tell.
The last picture looks like a Sea Squirt.

 

[frankness]

So neither are a pest?

 

[bang guy]

The Encrusting Gorgonian can be a pest. Anthellia can grow fast enough to be a pest but they are easier to handle.

Thanks Bang Guy! Do you think I should remove them or let them go for now?

 

[bang guy]

I would keep a close eye on them. If they start sending small runners everywhere then you might think about removing them. I guess it depends on how much you like them.

 

[frankness]

Ok I will do that thanks
