hydroids

ok so my duncan was closed for a few days i was like oh that’s fine then i noticed white stringy things and they retract when touched now i know they are hydroids and i know blah blah terrible spelling no commas i’m kinda in a rush atm but here’s what i did i took my turks- baster thing filled...

Got these things hanging around the corner of my tank. Can't tell if they're hydroids or something else. Can anyone help ID?

Hey guys so I’ve noticed some stuff on a zoa frag of mine and determined that they are hydroids, what can I do to fix this problem? Do I dip the frag or something? I kind of isolated the frag tonight on my frag rack because it has started to spread on my rocks any ideas or suggestions are...

I’ve been told by some they’re pods & some say they’re hydroids. Can anyone help confirm what they are & if they’re good or bad. Should I be worried & do I need to get rid of them? If so, how? Sorry the photo isn’t the best, but it was the best I could do. They’re all over my tank glass.

Found these on an older piece of live rock that was given to me. Tank is 2 months old and the suspected hydroids are not spreading. Moved the rock to quarantine tank just in case. Any ideas on I'd? They are tiny and evenly spread out on the rock.

Sorry for the blurry photo, it was the best I could do. Zoa is actually on the upswing. Acro is new. I'm thinking I may have some hydroids to contend with. Any chance these guys are feather dusters or something less problematic?

In past I had 3 outbreaks of these hydroids, they just to hard to kill 3 times I’ve nuked the tank with febenzadole but somehow they always get back stronger. There isn’t any known predator available in the hobby right until now, only a few nudibranches eat them but not available for us. I...

Can anyone help identify this thing that showed up today in my tank? I think it’s hydroids but have no idea if it’s good bad or something neutral. Any help would be awesome! I have attached a photo taken today Thanks!

How harmful are they? How badly do they sting. If so, do they sting humans? If removal is needed, what should I do? If removal is not needed. They're pretty dang cool

I have some colonial hydroids and they’re spreading fast. What’s the best way to get rid of these?

In the past month, I’ve been noticing more (what I think is hydroids) cropping up on my rock. Can anyone confirm? Also, noticed some tiny white specks on my glass, but it was hard to get a good picture. Literally look like tiny grains of sand on the glass. No distinguishing features that I...

So I have this stuff that has pretty much taken over my tank and I can't get rid of it. I'm looking for an ID and an eradication plan that is anything short of a total teardown.

I've got a Fluval edge 6g nano that's been up and running about 5 weeks now. No fish, just CUC and random hitchhikers. I noticed the first couple of d.hydroids a couple weeks ago isolated to one rock. They have since spread to most of the other rocks. Not infestation levels yet, but a good 6-7...
