Critter ID

[ldouglasreef]

Hello, does anyone have a clue what these tentacles or flagella like arms belong to? There is a very small gap underneath the micromussa frag and after I did a water change these tentacles reached out. I then proceed to test if they retract when they get touched, and they did.

Mind you I dipped this coral frag in a typical Bayer concentration solution twice with tank water rinses in between.

10ml Bayer / cup of tank water (10 min)
Tank water rinse (10 min)
10ml Bayer / cup of tank water (10 min)
Tank water rinse (10 min)

A flatworm looking thing came off during the rinse and hardened within minutes but apparently the dip didn't do anything to this... That is if it is something.

Kind of hard to tell due to the contrast between it and the plug but it could be a white micro brittle star.

Ah yes unfortunately I should have taken more photos before touching it. I took a short vid before I touched it.

My vote is micro brittle still

video is helpful, but I still cant ID it. they look like aiptasia tentacles to me, but that seems quite doubtful considering where they are.

Once my headlamp comes in I plan to take a closer look at the frag. Might use some small tweezers to able to get under the frag and see what it is.

Does it look anything like this?

It doesn't. Like @Saltyreef mentioned it looks like a micro bristle star but the tentacles float in the water column like it's fetching food rather than for movement on surfaces.

They do that
