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

[BrendaddyK]

Trying to identify both the green stuff, and the circular object in focus on the picture. The green is all over my glass. The snails seem to eat it because when a snail goes through it leaves a trail but they never quite get it all off. And the circular thing is very hard and has to be scraped off to remove. They're ccovering my back wall and a couple on the front and sides I usually remove.

 

[Sugar Magnolia]

The green stuff is algae, use a scraper to remove it. The spiral is a spirorbid worm, harmless.

Is this Marine Itch? It seems to show up better under different lighting.

Anyone any idea? Found it crawling tonight. Pretty funny that you see little critters poping out after 3 weeks [emoji13]

Hard to see any detail to positively ID the worm.

It looks like a baby bristle worm. Couldn't get it any sharper on my phone.

Help identifying please?

I found these attached to chato in my fuge. I'm not sure if you can see from the pictures, but under magnifying glass it looks as if they are egg sacks with white eggs inside. Any help identifying these would be greatly appreciated.

Hi all,

I've just set up my first marine tank after 15 years of tropical tanks. I was wondering if anyone could give me an ID on this little creature.

Thank

thanks

Yellow polyps
Sponge maybe?
Spinoid worms

No worries on any (save I was correct on #2)

 

[seahorsedreams]

#1 is actually colonial hydroids.

 

[elmersglue111]

Is this a blue aiptasia? I thought they only come in red and translucent?

 

[Sugar Magnolia]

It's aiptasia.

I believe it's Botryocladia, a kind of macroalgae, which is harmless

Found them after coral dip in Revive

I have those all over my tank, harmless worms, good cleaners

I have found something looking like feather duster but not sure, any ideas is it harmless:

Yep, it's a feather duster
