Some type of hydroids maybe?

Some type of hydroids maybe?

Hi, Can someone help me ID this? I thinks they're hydroids? Polyps? of some type (hopefully not baby aiptasia). See upper left corner of attached photo.

Thanks.

Hydroids, yes.

Anybody identify this lil fella? First noticed him crawling on my one live rock, 30 minutes later he was on my dead rock.

 

[alexander_ktn]

Might be some species of limpet (1st guess) or a stomatella snail (2nd guess).

It seems to be a coral/anemone? It has several flower like heads all attached together kind of like how a galaxia coral is. They do retract. I'm attaching two photos. One with them retracted and another with them out. The whole thing is smaller than a pencil eraser and is a brownish color.

it almost looks like a type of encrusting pavona hard to make out detail form pic though.

Is this starfish looking thing ok?

What is this, cant seem to swim, is running very fast on life rock.

Looks like a mysis shrimp.

Hi, do bristle worms swim?? Or is the another type of swimming worm? I turned on the room light and spotted what looks like a 2-3cm orange/pink worm swimming around the tank like a fish!! It's head was grey. I got a video of it but I'm not sure how I can post that on here.

The tank is just starting, it's not even completely full yet but I do have some live rock in there and powerheads/ heaters in there just keeping things ticking over till its full. Should I try remove it??

I'd say gammarid amphipod.

It might be an epitoke, part of a bristleworm that contains gametes and is used for reproduction. They usually swim rather fast and a bit erratic.

It's hard to identify on the picture - if it looks like a mini starfish it might be an Asterina - search the forums for it - they can be absolutely benign or they might irritate some corals depending on the situation. So it's a hard question to answer if they are ok or not.

Hi Alexander, thanks for the reply. I Google epitoke and agree that's most likely what it is! I didn't know bristle worms did that! Will leave it where it is

I noticed this morning I have very small white dots all of the front glass of my tank as the lights start to come on. They are moving around any ideal what these would be they are so small I can not really see the actual shape of them.

 

[alexander_ktn]

Copepods or something similar most probably.

Any idea what this is?

 

[alexander_ktn]

Any idea what this is?

A red algae - might be a Botryocladia, but hard to tell at this size.

Some kind of worm that is able to swim:

And was killed after getting sucked into pump.

Sorry about bad video, my phone was paused when I thought it was recording, so this is all the footage I could grab before it was killed.

Polychaete epitoke most likely.
