Hydroids

[T57spikes]

First pox, now hydroids, what's next!

Has anyone had success with peppermint shrimp to remove hydroids?

Hydroids are unharmed (depending on species) by peppers.
The first question would be can you explain what they look like or do you have a picture?
Hydroids are right up my alley!

Upon a close inspection yesterday evening I found them.

There seems to be two types or one is further progressed than the others.

When I get home I'll grab a few pictures.

I'll attempt to explain thought, and I have seen a few pictures on the web that are an exact match.

One set is the long extremely small white almost looks like a thread that has the fan at the end which looks similar to a feather duster but lacks the feathers for lack of better terms.

(Not my image) but looks to be an exact match as to what I have.

There is a solution to hydroids but choices need to be made :)

 

[Robink]

Tell us, I have them too.

I would just smother them with some epoxy. It would be like putting a piece of chewed up bubble gum over them. This will harden up and before you know it the epoxy will be covered in Coralline algae. You'll never even know the Hydroids were there. GL.

They are proving to be extremely hard to photograph with a phone, this is about best I can do.

The one that's in the green Zoas is much larger than the 5-8 that are to the left of the willy wonkas.

I'm still doing research on them, is there any consensus as to how they spread, I'm hoping it's not like aptasia.

Maybe this link will help.

Don't forget to click on the other links at the top of the page too. (Hydroid Identification, Hydroid Behavior etc)

Thanks for the links, I'll be doing a lot of reading tonight.

It's in a frag tank currently so my display isn't effected and if it comes down to it I can just shut the tank down and start over but there is some nice Zoas I wanted to keep in it.

I may try the super glue method and then to the Fenbendazole if the glue isn't effective.

Hey..Old thread, but rather than starting a new one wanted to see if anyone had means to control these. I have same things growing out of a Zoa frag.

Can I just pluck them out with some tweezers? just leave them be? They don't seem to be bothering the Zoa's much...yet. If its just the two or three stalks I don't mind, I just don't want to wake up one day and have them covering a bunch of corals.

If they are the kind that retract into a leathery tube, almost like a feather duster, look out. Honestly having shut down a tank over them in the past, I would sooner throw away a frag that had them than bother trying to get them all.

 

[nanofordad]

No tubes that I can see. Just tiny hair sized stalk and little 'dandelion' heads... I pulled one or two about a week ago, but now either same stalks regrowing or three new ones in same place.

The ones in my previous tank had a bluish green tinge to them and withdrew into leathery tubes. It was bad. I tried using straight kalk paste on them but that didn't kill them. I took a few of the worst rocks out and hit them with a torch to knock it back, but eventually it was a losing battle.
