Anyone know what these are?

[liljosh609]

I had a mini brittle star die a week ago and suddenly all of these things pop up. They look like baby mini brittle stars, but could they be hydroid jellyfish?

 

[fort384]

Hard to tell from the pic. Could they be asterina stars or do they have soft tentacles?

 

[liljosh609]

They are defiantly not those because it looks like they have almost hairlike limbs.

 

[fort384]

could very well be hydroids then. It is possible to get a closer shot?

 

[liljosh609]

This is the best ya gonna get.

 

[liljosh609]

Sorry. That's came out wrong...that's the best I can get.

 

[fort384]

ah yes, now I can see the tentacles. Looks like hydroids to me.

 

[liljosh609]

Ok. Are bad?

 

[fort384]

Yes, not good. I have never had them before, but to get rid of them, I have read they are tough to get rid of. You can use something like kalk paste or Red Sea Aiptasia X to get rid of them.

 

[liljosh609]

Ok. Are they bad?

 

[fort384]

Yes, they can sting fish and coral.

 

[liljosh609]

How can I get rid of them?

 

[fort384]

Like this

 

[liljosh609]

So I couldn't just kill them one by one? Also I heard they just go away on their own.

 

[mr_X]

I believe they will go away on their own.

 

[fort384]

That would be killing them one by one.

And, Mr X's opinion is more valuable than mine on this I have never had them, just read about them.

 

[liljosh609]

Ok. Thanks

 

[mr_X]

There are multiple types of hydroids. The new tank ones we see here, and others. These I believe will leave as fast as they came without a trace.

As I've read the colonial hydroids are the ones you have to worry about these look like the medusa hydroids that I've had befor I saw them for a week on my glass then I haven't see any since. It was also right after I bought a piece of live rock! Hope that helps
