Noob ID thread

[banjowalker]

I'm gonna go ahead and start my own thread for IDing critters and other things I find periodically. I added live rock and wouldn't you know it, little things are starting to move everywhere when the lights go out. Here are my first two I need help IDing

thinking this guy is a bristleworm?

I have no clue on this little guy. He was very fast. Reminded me of a roach honestly. Saw a couple of them and just barely got a pic of this one before he scurried to a hole.

Bristleworm and Gammarus (a type of amphipod). Both beneficial detrivores, but the bristleworm can irritate skin if you touch it. They don't bother some people, but they give me a red rash when I touch them.

They're both common, and imo, both good guys for your tank.

Great news! The bristleworm was kind of cool to watch, but I have heard some species can be bad. Thanks for the info!

The first one is a fireworm.

Update: I think the bottom might be a gammarus amphipod

A fire worm is harmful to a reef correct?

 

[Wiinberg]

No it's fine. Just don't touch it You probably have 10's or 50's of them.

It's a run of the mill, normal, ordinary bristleworm.

Got rid of this little devil today. He's the only one I've seen but I'm sure there is more

 

[fungia_fiend]

Asterina star. Some varieties are reported to eat zoos, but I've never seen it. I've had these for years and they've never been anything but beneficial.

I've heard all negatives about these so I just went ahead and got rid of it

I love them and will intentionally introduce them. I've never had an issue with them in over 15 years of reefing.
