Hydroids??

[daddio]

Peter and I were working on the reef tank today and he noticed hundreds of small white specks on the glass.

We think they are Hydroids? Should we be concerned?

I don't know for sure what that is but doesn't look like what I know hydroids to be

 

[daddio]

They are small, like a grain of salt/sand

I've seen those on my glass too. I'm curious what people come up with. My first thought when I saw them was baby aptasia. I don't think so anymore though. They'd be all over my tank by now if they were.

if that is a hydroid...KILL IT!!
they will kill all that you have paid for!
bad bad
very bad

unless...you like it
then grow it and feed it and love it

Relax I had a bunch of them too. They are hydroids but not the bad kind. I posted photos on this forum and then I looked over the Internet forums. They eventually went away on their own. Looks exactly like that.

After looking at pictures on google and RC; what they are calling hydroids I definitely do not have.

The hydroids I had(have?) were like little tubes all over rocks, not the vermedit snails, they were in very dense cluster almost like carpet, somewhat soft to the touch. But damnit if they don't spread. Worse of all, whenever I'd rub up against them it'd get very itchy with little bumps.

Wow, never realized they were that small.

Those are what I know as hydroids.

Like I said...

This is off melevs reef. Not like he's the Bible, but there are other random sources too. Whatever they are called, they are not harmful.

So I was looking at my Hammer before the lights cam on and was surprised to see this. Hydroids, right?

Hammer doesn't seem to be too bothered by them when the lights are on

So, should I try to remove them?

Those look like feather duster worms. Filter feeders, shouldn't bee a problem. I can't believe you didn't notice that many before!

 

[Gablami]

Agree, thought to be a good thing, right?

Yup feather duster worms, if you're that worried you can usually siphon them out as they are often very loosely attached.

Those on the glass are harmless.

These are another colony of hydroids that I kept awhile back. They didn't do much and didn't bother anything (nothing around them).

Well it looks as though our little fellas disappeared.

Mine went away after a week or two too.
