Hard to tell for sure from the picture but I think it's a stomatella. A good guy.

Thanks. I think your right.

Me again

Seems like every night now I'm finding a new critter on my rocks. I'm hoping this isn't a bad one. It was flat and moved very slowly. My guess is some type of flat worm. I sucked it out of my tank didn't want to take a chance. If it is indeed a flat worm can they survive in my tank even though I don't have any corals?

This is a batch of live rock that keeps on giving! I got about 10lbs from the LFS of this almost a month ago to cycle my new tank. Almost immediately, I found that it was riddled with Aiptasia and a small amount of bubble algae. I took the rocks out of the tank and removed all the aiptasia and bubble algae and put them back in.

All of the rocks but this one appear to have stayed pest free since my cleaning. A few bits of aiptasia came back on this one that I'll be removing shortly. When I was looking at the aiptasia, I noticed something else growing on the rock.

When you look real closely, there are a dozen+ of these very fine strands coming out of the bigger pores of the live rock. On all sides of it too, not just one area. To the naked eye, it looks like alternating bands of black and white going up the strand. They seem to be growing longer every day. This live rock has some bigger chambers inside that connect to the surface through smaller pores.

The pieces near the aiptasia came out the clearest in the picture. If anyone can identify this, I'd greatly appreciate it!

Looks like chiton. Not sure which one.

I agree those are brittle star fish. VERY good to see. Let them be and they will move around. The edges on their arms help keep areas clean plus they scavenge for things that fall in the rock.

I did some reading and I think it was a chiton. Regardless I took it out of the tank to be safe. I'll be keeping an eye out for more.

Thank you both. Glad to hear that it was something good! I'll be extra careful when nuking the aiptasia to try and not disturb these guys.

Is this a bristle worm?

coffee_snob · 01/25/2015, 06:43 AM

I must have posted this in wrong forum, didn't get much feedback.
Wondering if this guy should be removed.

Coffee_snob,

It is NOT a bristleworm.

That is a Spaghetti worm, out of it's protective area, normally they are hidden under the substrate or in a crack of a rock.

I've got a bunch of these things growing in my overflow, sump, and also some inside live rock crevasses.

Anyone know what these are?

Pineapple sponges. Common... they come and go.

chefbill · 01/27/2015, 07:47 PM

Bright green nem, pink tips. Very fast reproducer. Doesn't seem to bother anything. Ideas?[IMG][/IMG]

worm5406 · 01/27/2015, 10:16 PM

Majano it is a pest.

You would do best to remove it as soon as possible and keep up on removing as you see them.

chefbill · 01/27/2015, 11:22 PM

not so sure is majano. much more slender and elegant looking. Not as thick and bulbous as the others ive seen.

Socalreef60 · 01/28/2015, 12:41 AM

Maybe aptaisa then?

Majano is a general term used to describe a wide variety of pest anemones which is what you have.

chefbill · 01/28/2015, 08:38 AM

OK, good thing they are in a LFS. None of the reefers there ID'ed as majano. We all figured pest, just from growth rate. Damn, actually nice looking little nems.

Thanks ; )

I remember seeing something similar years ago on a previous tank. It could possibly be chiton. The one I had was well blended with the rock. Most chiton have their mouth on the bottom, so I can't explain the exhaust stack. But the dust or what I thought at first was smoke appeared to be coming from a short tube on the top exterior.
