Pix & ID: Critters that come in your rocks: the good and the bad.

[TankFan]

It's a pencil urchin, harmless grazer but can knock over corals that are unsecured.

Thank you for the ID. Appreciate the help!

Whats this thing. Is it some tyoe of snail? It has no shell

 

[Sugar Magnolia]

Stomatella. They do have a small shell.

 

[Dctrojan]

Keep?

 

[Sugar Magnolia]

Yes, very beneficial.

Can someone tell me what the bluish leafy stuff is and whether it's good or bad? Thanks!

 

[cloak]

Dictyota.

It's actually kind of pretty, but if it's growing a lot it might be an indicater. (too many nutrients in the water)

Just keep an eye on it. Prune it if need be. GL.

Thanks. I was convinced it was flat galaxaura, not that lucky though. Thanks again.

Ok all you critter ID people, what is this? It is crawling on my rocks an looks like a snail with no shell, an 2 antennae, a slug of some sort?

Can anyone ID this stuff?

Can anyone ID this stuff?

This stuff is all over the back corner of my tank. It is circular. I'm not sure if they are eggs or what they are. I have a mixed coral tank with LPS, SPS, and Softies in it. Just one coral beauty.

@Jivewalker that Dictyota is really cool looking. Is it naturally blue or is it because of your lights?

Harmless stomatella snail.

Looks like sponges, harmless.

Wondering if anyone can tell me what these are

Wondering if anyone can tell me what these are

since moving all my fish to their new larger tank, my 38g nano has millions of these critters in it. I'd like to feed them to my other tank if it would be good

 

[Sugar Magnolia]

Munnid isopods. You can feed them to the other tank if you'd like, but they are harmless and an excellent part of the clean up crew.

 

[sh0ck]

what kind of worm this can be? He is nonstop swimming in that cup.
I got him yesterday during night, swimming on top of the water.

So I just got ID Phyllodocidae
As I have many worms in my DSB and this one seems to be their predator, he will be probably staying out of my tank.

great thank you your input, id like to find something live to feed the fish and coral in my 150g. any suggestions on an easy way to achieve this?

This is the clearest picture I have, today. Tomorrow I will take a better one, to help with the ID.

Ideas, I know an urchin, was looking for a classification.

Thanks!

Edit:
Took a few more pictures.
