Thank you SushiGirl for helping me out on my previous identification!

Finally got rid of the 1,000s of Hydroid Jellyfish on the glass, and now I have dozens of these. Are they adult jellyfish, or something new please?

Any help would be appreciated.

Flatworms, the harmless kind (except to copepods LOL).

LOL, just my luck then! I bought some Chaeto a couple of weeks ago so I could start producing pods for an eventual Dragonet... Looks like I got more than I bargained for. Will my snails eventually off them, or will copepods outbreed them, or am I just out of luck for now?

[SushiGirl]

They may just die back.

[mgrmax]

Aptasia?

[SushiGirl]

Yes.

Asternia stars?


And what is this pink thing that has grown white on it?

Asternia yes, pink dunno but maybe someone else does. Reminds me of my pink sponges....but the white part throws me off.

[SushiGirl]

The pink almost looks like sponge I have that started out white (or grew over a white one LOL). The white tips is weird, though. Maybe a type of coralline that's bleaching a bit? Is it hard or soft?

Hello All,

Somehow this purple algae (?) got into my tank and is slowly taking it over. I was trying to clean corals as they were effected and it is getting ahead of me. Can anyone tell me what this is, and how to get rid of it...

THANK YOU !!

This is a small snail I found in my sump this morning. Tank has cycling for 3 weeks and there is much in my tank so I was kinda excited to find something alive . Just wanted to make sure it was a good hitchhiker before letting him out of jail. Thanks.

I think it might be a Columbellid snail.

awww he is cute. I love their snorkels. (I know they aren't really snorkels). Reminds me of my cowrie hitcher

[svoad]

Thanks for the info Cloak. So, I should let this little guy go on his way and do his job eating all my algae ?

Sounds like a stomatella snail. (harmless)

Wow its amazing what grows in a Reef Can you please help me ID the following & more importantly whether they are harmless or need dealt with:
1. algae.jpg - what is this algae you can see on edge of rock & who best gets rid? It is like a film over quite a few rocks now
2. cocoons.jpg - what are these 'cocoon' like things?
3. snail.jpg - this is weird looking snail. Possibly what they're referring to in post above? Anyone got a name so I can research.
4. unknown.jpg - hmmm ha my best guess would be a sponge? I have no idea. Also you can see a couple of small white things sticking out right next to the pinkish 'sponge' which is same as pic worm.jpg.
5. worm.jpg - as I said above this is actually the exact same area (without a light shining on it, its not really that dark just slightly shaded but my camera phone is crap) but you can see one of the small white things has stretched right out & is reaching/feeding?? on the substrate. There are around 4 or 5 of these in that area.
6. reached my limit for this post 1 left that i will post in a minute.

Thanks

Googled stomatella snail & looks really like snail I see in my tank so think I can mark that down as harmless & remove from list.

Last pic i couldnt upload on last post

white things.jpg - These 'white things' are on a few of my snails & are all over my internal filter. Should I be worried?

THanks

whiten things on snails look like feather dusters, cocoons look like pinapple sponges..both good

[ed84g]

I found this guy last night... Took him 3 weeks to come out and was a bit of a surprise considering how intimidating it looks!!

[ReeferKimberly]

ed84g that is an urchin..which you probly already knew....someone else maybe will know what kind.

Hey so I found this guy last night. Could not get a good pic so I drew him. This is just a little bigger than his actual size (about 2.5 inches long, 1.5 inch wide). It has the consistency of a snail, with NO shell of any sort. He must be nocturnal and he moved pretty quick (out of site before I could get the camera). Unfortunately I did not note if he had eyes or a mouth or what they looked like. He was completely flat. Any idea? Looked like this ->

(he was not completely oval shaped but that was the closest shape to him. Don't mind my awesome paint skills)

He was grey with white spots, yanno, if that isn't obvious :/
