I am no expert here. Is it Stomatella?

Thanks

Yes.

 

[trapline]

Is this a bristle worm?

Is this a bristle worm?

It's bright red with white spikes and gets blueish on the other part I have seen

Can you tell me what the white string like white worm looking thing is in the picture posted in #3056... I have several of these and they come out most of the time but not sure if bad or good??? Please help

 

[jedavis3]

I wish they'd either fix or discontinue Tapatalk.

To answer, probably not. Did it come in maybe a green coral? They typically look like what they eat.

Sushi Girl,

Thanks for taking the time to reply.

Yes, I can only assume that this nudi hitchhiked last week when I added a cluster of new green zoas. I'll remove it immediately. :uzi:

 

[Sugar Magnolia]

You'll want to inspect the zoa colony closely to look for more nudis and egg sacs.

This white thing appeared on the back side of the top of my rock. It is about the size of a golf ball and the tentacles or hairs are about one inch when fully extended. They flow in the current.

What is it???

Any idea on what this is? Only comes out at night and it doesn't move from this location.

Just a harmless sponge. No worries.

 

[TankFan]

mini brittle stars, they are good

 

[Ptyochromis]

Any idea what this thing is? I have seen it a few times before, it sora reminds me of an alevapora polyp.

I have lots of these attached to the glass. Is it a type of hydroid and should I do anything about them?

It's an Aiptasia, a type of anemone that will reach plague proportions if you dOnt get rid of them. You have to remove the entire organism, it can regenerate from small pieces of tissue. I like to use joe's juice. Coating them with kalk paste works just as well. You can try scraping them off the glass while you siphon.

I have a couple of big ones on the most recent rock I added but these teeny ones were there way before I added it and none of my other rock had any but I guess they must have been hiding! I'm getting a peppermint shrimp at the weekend as I really like the look of them anyway so fingers crossed he'll deal with the problem

 

[Yellow05gt]

Anyone ID this for me?

 

[Sugar Magnolia]

Looks like Phyllagia Americana. Cup coral. Harmless.

Indeed, ill second that.

 

[Yellow05gt]

That's good to hear. I thought it might of been a "pest" anemone and was about to get rid of it. Thanks a bunch once again!

Worm

I found a worm swimming around and then climbing on my coral (which concerned me). I removed it but I don't know what it is - I tried to identify but can't find anything that matches. See picture. Any guesses?

Thanks
