Bck2hobby · 05/01/2013, 10:42 PM

alexander_ktn · 05/01/2013, 11:18 PM

It's a small mantis shrimp.

ReeferKimberly · 05/01/2013, 11:25 PM

Yes it is and if I didn't live 8 hours above you I would want it so bad!

Bck2hobby · 05/01/2013, 11:31 PM

Thanks for the ID guys much appreciated. I thought it was at first, but didnt see it's claws. Hmmm I can already hear my wife, another tank for 1 shrimp

. Eegads now have to mcgyver a section of current tank to keep him away from rest of tank. So far had not bothered anyone in there.

GroktheCube · 05/01/2013, 11:55 PM

I've got a really weird one. A two toned, RAPIDLY swimming polychaete of some sort. When I first saw it in the tank, I thought it was a small fish. I have never see a worm swim this fast in my life. I have NO idea where it came from. I don't want to put it back into the tank until I know what it is, because a worm that swims that fast screams predator to me, but I'm worried it will swim itself to death in this cup.

Anyone have any ideas? I poked around on the internet a bit, and couldn't find anything.

ReeferKimberly · 05/02/2013, 12:28 AM

Epitoke maybe? It is a swimming stage of stuff, part of their reproduction...I think bristleworms included. I know others will know more than me about it though.

"Within a group of polychaetes, the syllids, the rear (backside) section of the worms is customized to transport either ova or semen. This epitoke at some point breaks away from the primary section of the worm, and swims towards the surface to recreate. As soon as the ova are fertilized, female epitokes carry the embryos in sacs on their abdomens until eventually they hatch. The rest of the benthic worm is termed an atoke, and may carry on feeding and growing, ultimately producing new epitokes. Syllid epitokes form astounding swarms of reproductive individuals at the surface waters. This fascinating conduct is considered to be controlled via the lunar cycle, having a peak close to the full moon.A different variation is observed in some of the tropical eunicids, where the anterior portion of the worm is filled with gametes and then breaks off. It then swims up to the surface when the ova or semen is released. This in turn leaves a portion of the adult still alive (the atoke) in the rock to repeat the process again. These are in fact true epitokes."

GroktheCube · 05/02/2013, 12:44 AM

Maybe. I always thought of those as being more stringy and swimming a bit more slowly and awkwardly. This guy is just ridiculously fast. You're probably right though.

ReeferKimberly · 05/02/2013, 12:50 AM

They are so neat! But I have no idea about like what worms do it and what don't and if yours is harmful or not. Just a particular stage. Always neat when these things happen in our tanks

GroktheCube · 05/02/2013, 12:52 AM

Yep. That's exactly what mine was doing in the tank. I've done some more reading, and I'm PRETTY sure it's a Nereid epitoke. Gonna toss it back in the drink. On the off chance it's something bad, the firefish will be going into the tank in two weeks, and hopefully they chow down :-p

SushiGirl · 05/02/2013, 12:24 PM

Epitokes swim crazy fast, and bristleworms do have that stage. Up to you to keep it or not, you'll have plenty of bristleworms either way.

Those last pics of the pod had me thinking mantis, too, but I also couldn't see claws.

Bck2hobby · 05/02/2013, 01:02 PM

I put him on time out till i decide what to do - giveaway/trade or keep

alexander_ktn · 05/02/2013, 01:41 PM

You can feed it with mysis or similar food and put some live rock/rubble in the container if you haven't already.

Bck2hobby · 05/02/2013, 02:10 PM

thanks for the info - first thing i did last night =)

bloodypeasant · 05/02/2013, 02:19 PM

Okay, I've got a small, flat, round guy roaming around my tank. First noticed it on my sympodium (the coral was retracted) and this brown spot was on it. Got me worried. I came back a few hours later and the brown disc moved off of the coral and onto my rock. Moves about as fast as a starfish (inch an hour) but has no noticable legs or appendages, its perfectly round. Was somewhat concerned since I saw it on the sympodium. Any ideas?

Ryphen · 05/02/2013, 06:53 PM

Looks like a fleshy limpet from the pic. We have one too. Safe grazers.

cloak · 05/02/2013, 07:44 PM

My guess would be a flatworm of some sort. Usually not good.

hogfanreefer · 05/03/2013, 04:35 PM

Found this guy today while on an aiptasia hunt. Hard on the top, soft on the bottom. About 1/2" at his longest dimension.

SushiGirl · 05/03/2013, 04:49 PM

Limpet. It's fine.

hogfanreefer · 05/03/2013, 06:22 PM

Thanks Sushi!

SushiGirl · 05/03/2013, 07:41 PM

You're welcome, Hogfan.

Glad to hear it! I think it's time well spent to look through the thread, answers a lot of questions before they get asked!

I thought you were talking to me. LOL. I was like hmmm yeah that is true I did do that but I don't remember saying it. geez, I need to eat. I am getting dumb (just saw the name Kimberly). Yes the first thing I did on this entire site was read this whole thread. I recommend making it so you view 40 posts in one thread, it is an option in the control panel. The thread is still soooo long but it makes it easier. I bookmarked the thread and read every word in a few days. Best thread on RC imo.

Tankssy · 05/04/2013, 03:44 PM

Yesterday we bought a Maxi/Mini Nem attached to this rock. Got her off and chucked the rock onto our rock/holding tank.

When hubby was looking in the tank for a rubble piece, he found these lot on that rock. They are about the size of pencil erasers. Normally when we get Aptasia its of the glass or long stringy red type. So if this is Aptasia its a new one for us.

So are they Aptasia or Majano or baby rock Nems? Just want to make sure before we do anything with em.

SushiGirl · 05/04/2013, 04:16 PM

Ooh, those look nasty. The tips aren't bubbled enough for majano, and they don't look like any maxi/mini I've seen (I've never seen babies, though). They do look like a nuisance nem. Lots of varieties of nems, even within the aiptasia group. I have seen aiptasia with bands on the tentacles like that before. Do they resemble your maxi/mini at all?

Tankssy · 05/04/2013, 04:35 PM

I have never seen a baby M&M..and no..not really looking like our maxi. These remind me of rock flower nems tho. Like I said, we only seem to get the glass type Aptasia which is why we are hummin n hawing on these. Might shove em in a wee beta tank and see what happens..lol
