hydroid

This looks like a hydroid of sorts, Taking over tank, rocks, agronite

I bought a coral and noticed hydroids all along the base of it when it was in quarantine. They were irritating the coral at the base and I had stn. I fragged the healthy coral bits into a new plug and discarded the old plug with the hydroids and all. I must have missed the tiniest polyp or...

These are in my refugium. Started out with the white one, then a couple weeks later, the bigger brown one formed. Now I’m finding a new brown one about every week or so. They retract if you get near them and they attach to either rocks or the sand. Started seeing these after I put a few pieces...

Hello everyone, what is this? I couldn't find what it is. Thank you

Hey all! Relatively new to the hobby with less than a year of experience. Noticed my lepto wasn’t looking too hot and shortly after, I noticed these guys hanging out on the underside of the frag. My searches through the forums lead me to believe they’re hydroids, but I was hoping someone with a...

Looks like mojano to me but want to make sure as it is next to a ricordea Yuma , can anyone help ID here are the best photos I could get it is very small right now

So I’ve had these in the tank for a few months now. They don’t seem to be irritating anything at the moment but they started to multiply in numbers quite rapidly so I started scrubbing and vacuuming out a large number of these white hair-like projections from my rock. I was convinced these were...

Hey guys, thanks in advance for any help. I’m hoping for some help IDing a wormlike hitch hiker based on description alone. I apologize I did not manage to get a photo of this thing as it only seemed to come out after lights off and it was super thin, the camera would not focus. I will try to...

Hello. I have a 3 month old 20 gallon tank. Also I am new in this hobby. I got two corals of the same lfs. I found on one vermatid snails and removed them as soon as I understood what it was. Now I found at a similar area on that hammer coral small formations , 1 bud with 2 hairs/ filaments or...

So I’m going from a 30 gal to a 55 gal reef tank and current problems in my 29 gal tank is that I have spaghetti worms and hydroids. I don’t want either in my new tank so my idea is to not use my previous substrate (elimination of some of the worms) and using new sand. I know with that my...

Is this something I should worry about?

Small colony of semi translucent tubes on a piece of rock I bought from the lfs. Each polyp seems to have exactly 4 appendages with nodes near the tips.

ok so i picked up a frag and it had some hydroids on it so i covered that entire area with superglue here’s a picture i’m just wondering if this will be enough to kill them

ok so now that i look at it will hydroids respond if i blast them with water because if they do i don’t think i have hydroids and i just sold everything for no reason and i could’ve kept my tank without getting everything that i just bought for my new 20 gal

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?

I’ve had some people panic and immediately tell me it’s aiptasia. Some have said it’s white cluster anemone, which I am leaning towards. Or some type of colonial hydroid.

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...

Sorry this post is all over the place. I found this thing on my glass last night and decided to take some pictures today. Any guesses would be great. When I lightly poke it contorts then whatever is inside goes back to a full circle...what could this be? And is this a hydroid? It looks like a...

I got some corals from WWC about two weeks ago. I didn't dip them upon arrival as I'm new to corals... I've kept them in a separate tank to monitor them. Here's what I see so far in terms of possible pests/hitchhikers. If you can please help me identify them and possible remedies, I'd be...

Saw this guy on my glass a bit ago, so I sucked him up with a small syringe and put him under my microscope. Sorry these arent the best photos, they were taken with my phone, I have a phone camera mount for my telescope but it doesnt work as well with the microscope, so I couldnt go any higher...

Came in on some coral. Sorry about the poor video. It is tiny and was really hard to keep it in frame. Good or bad? Do I need to try to find it and get it out? Thanks! If you can't see the video, let me know. I'm new at posting videos on Youtube.
