Is this aptasia? Never seen it colonize like this before

Colonial hydroids

Here's one that needs an ID. This came in on the side of a lobo brain. It's only about a 1/2" long and just looked like red coralline algae at first, until I noticed that each end seems to extend when the lights go out, and retract really quickly when you flash a light at it or tap on the glass. It appears to be some sort of filter feeder, but I've never seen anything like it before. I've had it for about a month and has never moved.

I just got a new camera and was able to really zoom in on it. Any ideas?

It's probably just a Tunicate of some sort. (harmless)

Sorry i couldn't get better pictures but this guy as soon as I turn on the lights goes into his hole! I see that next to his hole in the rock is getting clean from algae, but... this is my first week cycling this tank, what's gonna happen when I get corals in it? Will this worm or whatever it is going to cause me problems?

A more experienced posted might know better but it looks like it could potentially be a Eunice worm to me. What does its head look like? If you can get a pic of that or describe it, I imagine that would be helpful.

Sugar Magnolia · 07/20/2017, 12:11 PM

It looks like a harmless bristleworm to me.

Bristle worm. I like them, but different opinions out there. Add long add there in check no real problems.

anyone got any ideas what type of crab this could be? im struggling to find anything, and because i cant get a decent look / photo of him its even harder!

thanks in advance

Look up strawberry crab, stone crab and red rock crab. All 3 are US native and strawberry is from Hawaii

What exactly are you referring to? That picture is so big that I'm not sure where to look.

Sorry, I use mobile phone so pics are normal on my phone.
Have redone the pic and circled what I saw this morning. It seemed to be quite fleshy stuck on the back wall.

Does it move around at all? Maybe an Asterina star?

Matty Jay · 07/25/2017, 09:25 AM

Both the coral? And the snail came with my live rock. I'm honestly not sure what either are. The snail seems to have a tongue that's sticking out.

Matty Jay · 07/25/2017, 03:32 PM

I'm starting to think what i thought was a coral could be a tube worm?

No, it's definitely a coral. Protopalythoas I believe. The snail looks more like a Whelk too, which is usually something you don't want in your tank.

Is that the toxic one?

AlSimmons · 07/25/2017, 04:07 PM

Yeah, I believe they are a little poisonous, but that whole toxic scare has been blown way out of proportion IMO. You probably have a greater chance of getting into a horrible car accident on your way to the LFS than you do by getting poisoned by these things. FWIW I've been handling Zoanthids, Palythoas, Protopalythoas etc for years on end with my bare hands and have never gotten sick, but if your still concerned just wear protective eyewear and gloves when your working with these corals and you should be fine.

Thank you!!

Matty Jay · 07/25/2017, 10:27 PM

Got another one for you guys can't seem to get a definite ID. One of my rocks gave these little red strings coming out of a couple of crevices in the rock. This is the main area though.

AlSimmons · 07/26/2017, 09:21 AM

Do the strings move around at all? If so then they might be from either a Terebellid or Ciratullid worm, both of which are harmless.

Yes they go all over the place. Especially when the last lights go down.
