860 that's 95% a Cirolanid isopod. That's gotta go. I'm guessing by now you have no idea where it is at. It feeds on fish flesh. I didn't realize this post was so old... sorry

I have 2 hitch hiker starfish that came on a couple sponges I bought, they are now about the size of a half dollar and look like serpent stars. Are they safe?

Otherwise known as brittle starfish, the answer is yes, they are reef safe. I have one in my tank too, came in as a hitch hiker on a coral. Most of the time you won't even see them. They are normally quite shy.

Thank you, I thought they were brittle starfish, just making sure!
I'm about to take out the sponge, he isn't doing too good, but figured they'd be easier to catch if I needed to before I take the sponge out.

two items I was hoping to ID.

First, the object in the red circle. It's white, when I feed the tank I think I can see tiny filter feeders coming out of the tubes. It doesn't ever move, but I believe it is slowly getting larger.

Second, the object in blue.

It looks like some kind of spiderweb/roots that appear to originate from the round sponge like thing circled. I assume it's a filter feeder, but none of the other sponges in the tank have those root like things coming off of it. Any ideas?

AlSimmons · 05/26/2017, 02:03 PM

That white thing might be a Foraminiferan of some type. The rest of it just looks like sponges or perhaps fungus or bacteria.

Hi all. Can I get some ID help with the white, feather-like organisms on my Acan frag? Thanks!

They look kind of like Colonial Hydroids IMO.

I love my Hermit crab and snails! They make everything nice and neat! I wish they could do the same for my garden shed.

I'm assuming it moves? If so it might be a Limpet of some sort.

Is it hard or soft? If it's soft I want to say a Majano anemone, but I don't think that's correct. If it's hard maybe a Rock Boring Urchin?

It's a limpet, probably not a keyhole. But a limpet.

I think it a majano, but it could be an aiptasia, there is no way that is a rock boring urchin IMHO. I see them all the time when I snorkel in the keys. I even kept one for a year or so.

Do rock Boring Urchins have spines all over them? I'm not exactly sure if that's what this mystery creature is or not, but it almost looks like 80% of it could be buried in the rock. It's sure got the right color for it. Hmm.

Just to be clear, we are talking about the photos in post #5936, right?

Yes, they have spine all over just like most other urchins. And I've never seen such a small one boring into a rock. And the ones I see in the Florida Keys have black spines and reddish tests. But that doesn't mean ones from other locations might not look different.

But this looks more like a zoa than an urchin to me. Which is why I said majano or aiptasia.

mwrobers · 06/03/2017, 09:56 AM

Thanks for the responses AlSimmons and Ron Reefman. Creature was out again this morning. Moved entire body out of hole in rock and moved at a decent pace. Possible an urchin, not an anemone. It's moving in the attached pics and has many thin tentacles/appendages radiating from it's core. I haven't seen any urchins with rounded spines, so still curious as to what it is.

Ron Reefman · 06/03/2017, 11:29 AM

Much better pictures and I think Al is right, it is an urchin (BTW, good job Al). There are urchins with rounded off spines and they all have the tentacles with small suction cups at the end so they can hold on to things. You can see them between the spins on this urchin I collected last week.

When I first got my hitchhiker urchin, he looked like this

3 months later

And now he's size of a softball. Been this size for over a year I'd say.

ZoeyStorm · 06/06/2017, 09:14 PM

I'm very new here and I'm not sure if I fit in even because I have a freshwater tank not coral but found this site while looking for information on taking care of and maybe breeding shrimp. I just found that one of my ghost shrimp has a worm and I need to isolate it before it kills any of the other shrimp and makes the recent deaths of two of my RCS more suspicious in hindsight. I've taken some pics of a few of the other shrimp as well as the sick shrimp, tho I haven't caught a pic of one RCS and one of the adult ghosts was being annoyingly discreet hiding in the back middle of the tank at the very hardest place to get a decent photograph of it but I tried. If people can comment on shrimp genders that is useful info too, especially for any non ghost since I don't want too much of a population of them...Prefer the colorful and more interesting (rather than creepy lol) looking shrimp.

ebjorklu · 06/12/2017, 09:29 AM

I just caught this guy on top of my live rock of my DT today. (I know the photo's aren't the greatest, had to do a full zoom to get this close, so it's pretty grainy.)

It's probably about 1/8 inch long (under 4-ish mm).

I thought it was something bad at first, and was going to take it out. However, after looking closer I'm leaning toward it being a baby (or maybe shell-less?) snail. So for the time being I left him in my DT...

...but if anyone sees any signs of this being something bad, let me know.

Thanks

Very blurry. Look up images of stomatella snail and see if it's a match.
