aiptasia

[surfingdude]

does these glow under fluorescent...i have a very small something that is on my toadstool rock and its glowing. went to to go after it and it just closed up completely...very tiny.

I believed they pop under blue light. Look closely at it, does it have pointed tips or bubble tips? if bubble then it is majano. Mojano are a bit more colorful than aiptasia.
Use kalk paste to kill it.

Pics?
Maybe a colonial hydroid?

I don't remember aiptasia fluorescing but its been a while..
Hydroids do though.. I've got a few patches of green glowing ones now..

Aiptasia are usually a dark brown color. I don't think they would "glow". It sounds like it could be another coral growing or mojano.

it is so small, tough to get a picture...i treid turning the the white lights on to get a pic but bam, it went in...even if i get close, bam! in again. and its spontaneous, like a nano second to completely retract. I can get a pic with blue but just hard to make it out. Once its in, you cant hardly see it except for a small flourescent dot, size of a pin head...when out, its 3 or 4x the size. If aiptasia, dont think it would retract spontanuosly. whatever it is, its very skidish.

could be a clove polyp?

Feather duster maybe?

[jayball]

the chlorophyll in aiptasia will show red-orange florescence under UV LED's (actual UV, under 380 nm, not 405 nm Near UV) but I have never seen it with GFP.

Without a picture I am going also going to guess hyrdoid (I have had these show up florescent green under blue LED) or a polyp of some sort.

mojano do glow under blue light. got frags from someone last week. has 2 mojano on them, under regular light couldn't see them under blue they glowed very green, they where actually very beautiful, almost didn't want to scrap them off with a razor blade

[mcgyvr]

neither aiptasia nor mojano have the "bam" response rate as stated by surfingdude..

[ericarenee]

i think its a tiny Feather worm polyp or something similar if it retracts that quick just by introducing some light...

[surfingdude]

Here is the pic...iam thinking feather duster too. Whatever it is, every time I get near the darn thing it literally vanishes in a sec. May just wait it out and let it grow and see what happens. This was my first toadstool and had it for a month and half and didn't notice it until last night.

The white-ish thing in the center of the photo look like feather duster.

That's probably as big as it will get. They do readily reproduce so you may wind up with clusters of them. Filter feeders

can i suck it out with a baster...its small

You can try to suck it out, or scoop it out if it's attached to a bigger piece of substrate. If not you can cover it with kalk paste if you have kalkwasser. There's several effective ways to remove/kill them, if it's just the one probably easiest to remove it manually.
