Mysis shrimp??

alexander_ktn · 02/19/2015, 02:49 AM

It's a gammarid amphipod - part of the cleanup crew that develops in tanks.

Oh cool, cheers!

LAMBrose1994 · 02/19/2015, 12:32 PM

Can anyone ID this please. It's on the left side of the photo on the wall, I don't know how to explain it but to me it looks like round balls with black dots in could this be snail eggs?

Are they good or bad :-)

Thanks Everyone :-)

I see a sea squirt near the bottom of the wall, on the right of the image foraminiferans (pink) but not much more...

Ah cool thank you not really thought much of them.

I've not seen it here before. I've circled it incase that helps its tucked away in a little crevice. Hmmmm :-)

alexander_ktn · 02/19/2015, 12:48 PM

That's the sea squirt (ascidian) I mentioned...

LAMBrose1994 · 02/19/2015, 12:57 PM

Whoops! I got little confused there, thought you was talking about something else but that's great thank you I was getting worried that that unusual specimen was :-)

Thanks :-)

alexander_ktn · 02/19/2015, 01:02 PM

You're welcome! It's because I tend to write everything into one long sentence - can be a bit ambiguous sometimes...

BTW the sea squirt probably can't be identified to a species level but the foraminiferan I talked about can with some certainty: it's Miniacina miniacea as far as I can tell - they look nice and sometimes survive in our tanks.

Snowdawg · 02/19/2015, 05:25 PM

I have seen three of these small green things in the past couple weeks. Two were attached to the base of a birdsnest, and this one was attached to a hammer coral frag. They are very firm and don't "pop" easily. Any ideas?

alexander_ktn · 02/19/2015, 05:28 PM

Bubble algae - Valonia sp.

m1k3 · 02/20/2015, 02:54 PM

Critter #1, is this a mojano or maybe aptasia?

m1k3 · 02/20/2015, 02:58 PM

Critter #2 the thing in the middle of my acans? What the heck is it? There are a couple of them coming up between the heads.

cloak · 02/20/2015, 02:58 PM

Aiptasia... The second one looks like a barnacle. (harmless)

Thanks! Great... My first pest...

Deckerd · 02/20/2015, 05:56 PM

Anybody knows what this is?

alexander_ktn · 02/20/2015, 06:14 PM

An anemone with puffed-up foot. I'd guess something like Aiptasia. They inflate it when they want to move (i.e. "swim" in the current).

Deckerd · 02/20/2015, 09:23 PM

Well took my chaeto out. As it appears its hundreds of them.

jpmwjm · 02/21/2015, 08:41 AM

Ok ... I've had my tank running now for abt 2 years .... Have found several 1/4 to 3/8 holes or burrows in sand. Never saw the culprit til this morning. Anyone know what kind of worm this is? I didn't get a pict when he was extended out about 1-1/ ....but he was able to move the small piece of live rock he's under.image.jpg

Puffyluv · 02/21/2015, 09:05 AM

Oh, no, it looks like a bobbit worm!

I rarely react like this to anything I find in a reef tank, but those things are frightening! Be very careful when removing him, please!!

jpmwjm · 02/21/2015, 09:22 AM

Thanks.... After your post I looked up Eunice ( bobbit worms) he appears to be lighter colored one and In two years he hasn't seemed to bother anything as of yet... I'll try to keep a eye on him. As long as I don't start having a losses is there a need to remove him now ?

alexander_ktn · 02/21/2015, 12:54 PM

I agree it's a eunicid - I recently removed one and all corals that were closed or sulking before opened up again, no more disappeared frags and small fish etc.

They grow immensely huge generally and will start bothering your livestock in the long run - if you want to keep the worm put it into a refugium or extra tank. They can be very interesting animals but due to their behavior (building a nest, redecorating the tank, having a large appetite) they are definitely the opposite of reef safe.
