Is it a pest do you think?

alexander_ktn · 02/13/2014, 09:04 AM

It might well become one, but it's very hard to say. Apart from the greenish mouth and the lacking zooxanthellae it certainly looks very similar to the aiptasia anemones we hate...

Yellow05gt · 02/13/2014, 09:05 AM

I thought the same thing, but I thought aiptasia was brown. This one is clear and the arms are more tubular

alexander_ktn · 02/13/2014, 09:13 AM

I don't think you'd risk much if you wait and observe a few weeks - that's what I'd do to be honest... (But I am a notorious wait and see type of guy, leaving crabs, worms, small mantis shrimp and everything else in my tanks until proven guilty

)

Hey guys,

Just got a fresh batch of live rock in today and one piece came with this clam on it. Anyone know what it is?

It started opening once the lights were off but it's easily scared

It'll be one of the oyster-type attaching bivalves rather than a clam. I can see obscure ribs on the shell, which make me think it's probably a Spondylus.

Cheers,

Don

Sorry not the best picture but any idea what this is? It started off tiny and now is quite large?

Sorry you didn't post anything?

ReeferKimberly · 02/13/2014, 04:39 PM

Tapatalk pics do not show up for a lot of people unless someone quotes them. I really don't know why. I was quoting so the pics would show up.

Reeffwkeeper · 02/13/2014, 07:40 PM

I believe that's lobophora.

It's a Padina sp. Macroalgae.

apreich · 02/14/2014, 12:22 AM

I thought bristle worms ate small inverts? I kept finding dead inverts in my tank until I got rid of the bristleworm. Prickly little bugger.

Sevenhours · 02/16/2014, 09:17 AM

Anyone able to ID this shrimp?

I am new to saltwater tanks and just curious as to what this might be. I think it could be coralline algae, but I figured it couldn't hurt to ask you guys what you think. Sorry for the poor photo.

It's a new tank that's been cycling for about a week. It was on there when I got the rock and it's a pretty vibrant purple even if it doesn't look it in the picture. Doesn't look like it's dying off or anything. There are a few different patches of them on various rocks. It's Fiji rock, btw.

Also right above it is quite the odd bit of.... something... hanging out in that hole right above it. I always assumed it was a calcium tube or something (because of how it looks from the side) but having gotten behind the tank to take the picture, as you can see, it's a bit flat and looks solid.

alexander_ktn · 02/17/2014, 03:08 AM

Are you sure it is a shrimp? Looks more like a worm to me.

Sevenhours · 02/17/2014, 03:20 AM

100% sure it's a shrimp sorry the pictures are terrible

He's some more if it helps

alexander_ktn · 02/17/2014, 03:37 AM

Thanks! I'd guess it's some alpheid (pistol shrimp) or stomatopod (mantis shrimp). Should be easy to tell apart if you look at the head, but it's too blurry to make out in the images...

If it is very small it could also be something in Tanaidacea, Anthuridae or some other small crustacean.

Yellow05gt · 02/17/2014, 03:40 AM

any ideas ok this black and white worm looking guy?

alexander_ktn · 02/17/2014, 03:44 AM

Looks like the feeding part (called "introvert") of a sipunculid worm (=peanut worm). They are harmless detritus eaters.

Yellow05gt · 02/17/2014, 03:56 AM

thank a bunch for the quick response!

syedjilani · 02/17/2014, 05:35 AM

Nice Thread....tagging along.

chrissfoot · 02/17/2014, 02:38 PM

Can anyone identify my latest hitchhikers. I think they are some kind of anenome (one of which is splitting). They have migrated the full length of my tank from some Live rock overnight!
