Keeping a sea cucumber...

[MikeP471612]

I picked up a fish from a guy that is shutting his tank down. While I was there he gave me a sea cucumber because he was desparate to get rid of it so he could start tearing down the tank. I have't found much info on them, what are they like to keep? Is there anything that I need to worry about? I usually research anything before it goes in my tank but in this case I didn't get a chance.

Thanks

More details, please - there are different kinds of sea cucumbers. Or a photo.

Links to the articles with photos:
Toonen, Rob:
Sea cucumbers - Part I: The Medusa Worms.
Sea Cucumbers - Part II: Sand-stirrers.
Sea Cucumbers - Part III: Sea Apples.

You can also try Google Image search (or any other) for the sea cucumber, and add color - you could see your cucumber there (I did).

Those are some great articles Dendro, thanks.

Here's another site with pics and descriptions.

Class Holothuroidea
Sea Cucumbers, and if you scroll to the bottom you'll also find links with info about many inverts. Look around there's also a section about fish.

He is a black one. Saw a little bit about them on liveaquaria.com. I will look at the links you guys posted.

Thanks

If it is sand-sifting, then it have to have just a sand to feed on:

Mine of different color, but principally does the same. Hides from strong light:

And, if the heaters are not in the sump, better to cover them:

Good luck!
