worm like

What is this on my glass?

How many of you have these living in your tank, forever? Pretty amazing stuff. Who knew?

Just woke up this morning and got ready to do my daily zoa growth picture and I found these little guys on one of my frags. Should I be concerned, my zoas don't seem to be closing at all. They're white and have very small antennas from what I can see.

Anyone have an idea what this is growing from under one of my zoas?

Is this something to be concerned with? It this more than one worm? Its about an inch and a half in length. I've never seen anything like it, any info or guesses would be greatly appreciated!

hey guys i just bought a couple of zoa colonies and noticed these tentacles tucked in between today. theres about 6 tentacles that all seem attached to one thing somehow? i just want to know if it’s harmless or not! heres a video of it moving and an image attached. thanks!

Found this weird white growth? Worm? On my frogspawn. Honestly not sure what it is. Attaching some pics. Any ideas?

I was brushing off an acan that is like 50% dead and I didn’t know why it was dying. All 4 other acans look fine. While brushing it off I noticed something shot out of it. Then landed on my rock. It was a worm of some sort so I used a turkey baster to suck it up and put it in one of my test...

I passed by my tank when the lights were off and noticed these worm like things on the glass. I removed from what I can see but sure there’s plenty more. I do not know what they are or if they are harmful to my coral any information would be greatly appreciated. Thanks

Does anyone know what these little buggers are? They are very, very tiny. This is the best photo I could do on my phone. They seem to multiplying rather quickly.

Last night when I was looking at my nano tank I noticed this worm looking thing trying to swim around but it was being carried by the return’s current. I captured it and here is a picture and a video. Any idea what it is? Could it be a pod since I have seeded this tank. If not, is is harmful...
