I don't think this is the sand shifting black sea cuke that you guys are looking for.

I see one LFS in Sugei tengah sell a lot of it. It has filter feeding tentecles that similar to sea apple.

[Terryz_]

Bum... Does it have feeding tentacle taking in sand...

Baby black cuke which ran away from his parents?

[arcanehacker]

I think these types are similar to the yellow cukes:

They are filter feeders.. rarely moves around.

its more purple than black.
