Title: Colonial Hydroids
Post by: Wall_Tank on December 17, 2017, 17:45:42
EDIT:  I change the topic name, to make it easier to find later.


This has taken over lots of my rock.  Any ideas what it is.  The 2nd picture is them retracted.  The tubes are semi rigid.

Ive got those too Walltank. They’re not spreading fast at all, but they are becoming a nuisance.

Could they be feather dusters or hydroids?

That’s what the look like. Really small feather dusters. Lots of them.

Doesn't look like hydroids I've seen.   They don't look like the normal feather duster either.   There is a noticable ring, with the hair like tentacles coming from the ring.

Upon more research, this apparently is something in the tubipora family.

Lazy, is this the stuff you were talking about?  https://www.reef2reef.com/threads/here-it-is-fenbendazole-use-against-hydroids.214950/

Paul, I took some sharp bladed tweezers to my little colonies. They pull right off the rock. It reminded me of dry peat moss. They may come back but they are easily removed.

lol...if I showed you a full tank shot, you might understand why tweezers might not be an option.

When I treat the tank, I'll shoot a few pics and post the progress.

They are colonial hydroids. They will take over and sting and kill corals.

Interesting, thanks for the ID.

Funny how I could never find a pic just using Hydroids, but put colonial in front of the word.....and sure enough, that is them.
Title: Re: Colonial Hydroids
Post by: Wall_Tank on January 27, 2018, 14:19:27
Figures....the day I wanted to start the treatment, my cucumbers have decided to sleep in the rockwork.

I'm going to move as many of the inverts that I can to the frag tank.....I'll isolate the frag tank during treatment.  I'm a bit nervous about my serpent starfish......he has been with me a long time, but there is no way to get him out without tearing the tank apart.

Did u try luring it out with some food?
Title: Re: Colonial Hydroids
Post by: Wall_Tank on January 28, 2018, 11:52:51
They are all nocturnal.  And since it has nearly an 18” reach,  it doesn’t have to come out.

Post by: Wall_Tank on February 11, 2018, 22:49:38
Started treatment today....about 6 hours in, and some of the hydroids are fully retracted, most are partially retracted.

So far the tube anemone seems to be okay.....it was rooted under my base rock, and wasn't going to move.

Dosage was approximately 2 mg/gallon.   ( https://www.amazon.com/gp/product/B009TAQ4OI )

At 14 hrs, all of the hydroids are retracted.

At 48 hours:
    The tube nem started to look not so good, but it released itself from it's tube, so I was able to get it out of the tank, hopefully it will recover.

    The hydroids have been mostly retracted this whole time but the are still sticking out the of the tubes a little bit.

At 72 hours:
    Not much change.   So I re dosed the product.

Well after 2 x 72 hour treatments, while they are retracted, most are still there, and will probably live.

I guess I'm left with manual removal or replacing all of the rock in the tank.    :angryfire

Would a 3x-4x concentrates dose be effective? Is it expensive or anything in tank you worry about?
Title: Re: Colonial Hydroids
Post by: Wall_Tank on February 18, 2018, 09:28:51
Perhaps, it’s not terribly expensive.  Everything im worried about is in my frag tank, which I isolate during treatment.  Going to do a water change and carbon.....see what really survived.  Then hit them again.

Could you bleach the rock?  I have done it to remove nuisance zoas/Xenia. BRS has some good steps. I like it better than acid.  Used fresh water bleach, fresh water rinse, salt water rinse both with prime. I’ve got test strips and brutes if you want to try it.

I think 🤔 I did about 4 weeks , but 2 weeks might do it. Crystal clear rock now.
Title: Re: Colonial Hydroids
Post by: Wall_Tank on February 18, 2018, 19:03:17
Sure I could but since it is on every rock, I'd have to empty the tank to nuke it.
Title: Re: Colonial Hydroids
Post by: Wall_Tank on June 02, 2018, 14:54:23
For the record, I found nothing that worked....it is back in full force.  Nice green wavy carpet on the rocks.  Time to replace the rock....

I have a few of these same hydroids. After reading this thread, I decided to take care of them before they get out of hand. I used epoxy to cover the majority of the patch and a laser to zap the ones the epoxy missed. After a couple days, the ones I have lasered are still gone. Thought I would share if this would be helpful to anyone.

I’d like to know what fuels it. I’ve had a couple little patches of it but nothing I got concerned about and it hasn’t really spread. But Paul sounds like his is the opposite.

Hey Paul, what did you end up doing about the hydroids? I currently have the clubs laser and it seems to have obliterated a small patch in my tank. Have you tried it?
