@Psiber_Syn that's probably a tanaid isopod.

I think this is a sponge but am not sure. Sorry about the poor photo. It is white and about 3" long. Doesn't move and has grown in a low flow area behind the rock wall. Thanks for your help.

 

[michaust]

are these good or bad

 

[kbourque]

Any idea what these are?

 

[Lionfish Lair]

@kbourque, hydroids.

 

[Lionfish Lair]

@michaust, are those snails? Maybe take one out to have a look. It has the rope pattern and markings of a collonista sp.

What's this growing on my ric.

 

[SandJ]

These are on my zoanthids (may be other places but that is the only place I have seen them). Zoas do not seem bothered.

They are extremely small (1/4 the size of a small flea if that big).

White

Seen crawling/moving on the zoas

Microscope picture was taken using 10x objective lens and an iphone held up to the eye piece

He legs can retract into the darker part (think of a clam shell closing)

Will try to upload (bad) pictures of them on the zoanthids.

@SandJ, it's an Ostracod.

@SandJ, it's an Ostracod.

That is it! Thanks! I am assuming they are ok? My google search did not produce may results.

Here they are on the zoas. They are the white dots near the top of the zoas. That is a 1" frag plug for size reference. Picture is just a screen shot from a video, so not the best quality.

 

[Lionfish Lair]

Oh ya, they are cool to have. I had some.

 

[smokin'reefer]

Not sure if good or bad but I'm assuming some type of anemone. Any help would be appreciated.

 

[Reefing Madness]

Aiptasia, gotta go.

 

[smokin'reefer]

Any suggestions on best way to remove. It is on a piece of tube coral and I tried plugging off with epoxy but it keeps finding it's way back out.

Put baking soda on it then put on regular super glue. You can google the baking soda supper glue trick. It wont come out of that.

 

[smokin'reefer]

Got it. Thanks. Will give it s try.
