I've taken to spending a couple of minutes each night observing the goings
on of my tank with a flash light. Along with the various worms and
crustaceans moving around the rock, I found a peculiar creature that I can't
find any details about by searching the web. Hopefully someone will
recognize it, given the limited details I have (and no pic).

It's a small translucent blob, maybe a half inch across that's attached to
the rock. It appears to be mobile, as it's moved about 2 inches in the last
couple of nights. In the dark it exudes long (about 3 to 4 inches)
tentacles. The tentacles have tightly spaced hairs, maybe 1/2 an inch long,
hanging off of them. When I hit it with the light, it slowly retracts these
tentacles back inside itself.

Any ideas what it is?

Thanks!

Regards,

Dave.

It doesn't look like it. It's more of a clear blob (no brown colour), and
the tentacles I spoke of are very long and thin. I don't think I'd be able
to get a photo because the tentacles are difficult to see even with the eye.
Plus, there are only 2.

Thanks though!

Regards,

Dave.

Sounds like a ctenophore to me.
