Is this a eel, snake, or whatever and is it bad?

[Russell Casey]

Hi,
New to the reef community and have looked through many posts but can't find this creature. My tank is officially cycled, so I purchased a hermit crab and a blenny. I put them in the tank. The next day they are nowhere to be found, they might be hiding as I have live rock. Anyway I started looking in the tank with a flash light in the rock and this thing scurried by it was about 8 inches long or so. You can't tell from the photos but it is inside a rock and on the other side.

what the heck is this and is it bad? How do I get rid of it? Any thoughts please let me know, I did install live rock in this tank from a live fish store. They had the rock in bins with a heater, and saltwater running for months.

Thank you,
Russell

Yea, looks like a air bubble..

I agree it looks kinda like a air pocket.. if it is a worm it might be a peanut.

Yea, looks like a air bubble..

Assuming the OP isn’t lying, air bubbles aren’t 8” long and don’t move. Lol

Air bubbles can be any size or shape..

 

[GlassMunky]

Lol ok sure but they generally only move up not sideways or jerky like he described.

Lol, an air bubble can come in many sizes... you can clearly see the bubble. Trapped air under a rock is not unheard of in a tank filled with water.

Face looks like an eel to me...mouth open. Back part looks darkcolor with light colored stripe.

To the OP, just lift the rock and rotate it, it will just float to the top. Putting porous rock in a tank with water will create air bubbles. It's even reflective, like a bubble.

If it is an eel, then the third picture down in the top left corner are all the baby eels. That, or it is air trapped against his rock; "air bubble" in scientific terms.

It looks like an eel to me as well. That is the way eels peek out of their holes and have their mouth open. Which by the way they will eat anything that can fit in that mouth! I once had a snowflake eel eat a fairly large clown tang.

Poke it and let us know what happens, legitimately curious!

 

[ReefQueen]

I have never seen anything in my life that looked more like a bubble lol. I have seen trapped air sort of “scurry” across the bottom of live rock from being pushed by flow.

Eel or air bubble? We may never know!

But while we're at it, can anyone tell me what color this dress is?

Begrudgingly, changing my vote to air bubble.
and I don’t believe Bigfoot exists either...lol
