Found a sea cucumber.....

[Reef_Daniel1527]

So I don't know how this guy made it to my tank, or how long he has been a resident, however I just noticed him today. Thought it was a giant bristle worm and pulled him out and realized it was a sea cucumber.

Any suggestions?! Good?! Bad?!

Looks like a harmless/beneficial Holothuria (sand sifter/tiger tail)

Yup, tiger tail. Let him stay.

Cool! They're great additions.

Had one for a long time. Pretty interesting to watch him work. All he does is eat sand and poop clean sand. One time it did wander to the top of a rock pile and "œstood up" waiving around. It appeared stressed and started spewing some "œstuff" around, which I understand is a stress response and not great for the tank. I removed him for half a day, then reintroduced to the sand and he went back to normal ever since.
