In Gary's livegoods for sale thread a few weeks ago he was selling a yellow cucumber,maybe he knows something about them ?

[scary gary]

Sounds like a cucumber. Any pictures? The bigger cucs can be toxic to fish if they die or are attacked.

I've got a black knobby cucumber. seems to be doing ok. it's turds look like rabbit pellets made out of sand. Gary ordered it in for me from J&L a month or two ago, it's about 6" long now and healthy as a canadian beaver!

I've got 2 black knobby cucumbers, 1 is allmost 1/2 the length of my 180G streatched out, and the other is about 6 - 8" in my 75G. Never had any trouble with them.
Some info on the 3 more common types...

Holothuria - Black Knobby Cucumber
Holothuria feeding on the surface of a sandbed in the aquarium. The cucumber feeds by mopping the surface of the sandbed with its palmate feeding tentacles and lifting any particles which are small enough to easily ingest. The animal then digests the organic detritus and any surface film (such as bacteria, diatoms, benthic microalgae and cyanobacteria) from the surface of the sand and help to keep the sediment surface bright and clear of organic buildup.

Impatiens - Tiger Tail
Holothuria (Thymiosycia) impatiens, a Caribbean species that is often offered for sale in the hobby under the name Tigertail Cucumber, is an excellent generalist detritivore that shows little preference for substrate types, making it an ideal choice for the aquarium. Being one of the most active species of cucumbers, H. impatiens does a great job of cleaning detritus in the reef aquarium, but this activity level also makes it more likely to encounter a pump intake or overflow, and because this cucumber also possesses Cuvierian tubules, such an encounter needs to be prevented by the aquarist.

H.edulis - Pink Cucumber
Holothuria edulis is another species that tends to be more common in the food market as trepang than in the aquarium market, although this species is seen far more commonly for sale in North America than T. ananas. H. edulis lives openly on the sediment surface in sandy regions and sea grass beds throughout the Indo-Pacific, where it grazes on organic detritus and microorganisms from the surface of fine sediments. H. edulis does not tend to thrive in captivity unless housed in very large (> 100g) reef tanks.

Hope This Helps
