Yet another aiptasia ID post.. sorry! Not entirely sure

[lba4590]

I found this tiny little thing on a frag. I’ve had aiptasia but it’s been clearly brown and less “perfect” than this. It’s white/clear with straight tentacles that don’t appear to move. Thoughts?

You can get clear ones like this if they aren’t getting a lot of light.

There’s many aiptasia varieties. As Garf said, not enough light can make them look clear.

hydroids, or something else?

My wife's 13.5 gallon tank has recently developed a large number of these little critters. I suspect they are some type of hydroid based on other postings and google image searches, but I have not seen anything that looks exactly like the pictures below. The heads are about 2mm in diameter...

From the links I give there, if you match it to any of them..., then it's aiptasia
Can't confirm at the moment and I'm not 100% sure, but it look like aiptasia

Very carefully kill the bugger.

I believe this is a hydroid in the photo

If I open the image and zoom it, can clearly see around the white tube like, is more mass which is translucent/clear. That's one of the reason to think it's aiptasia (which to me appear to be the gut, looking like a stalk. And the second: usually the hydroids tentacles aren't coming out think at the base and very thin at the end. But only that I can see from that photo.
Can you please get another photo, different angle Please, it will be very helpful (if need make few shots and if you wich change the color of the light), just we to be able to confirm it 100% for you if you wish
