I believe all cucumbers have some level of toxicity, otherwise they dont have a chance from a defensive aspect...
what are you worried about, I havent ever heard of a dead cucumber causing a problem, and I have heard of alot of dead cucumbers...

I have a black one in my tank right now..its pretty large and also one of those nice yellow one that just stick on the side of a rock,...they both havent done any damage yet but hey none has died yet..
 so i wouldnt know, but i heard those yellow ones are more toxic than the black on...

I have two tiger tails in my tank, they are always in the rocks and never on the glass.

They are definately toxic, but it depends how they die. I had my tank setup for about 6 months, and had a pink/black cucumber about 8" in my refuge. The cucumber crawled up the glass into the compartment with my skimmer pump (mag12). As murphys law would have it, I was out of town for 3 days, cucumber got sucked in to the skimmer pump, and about $300 worth of fish were dead. If I would have been home, I could of done water changes and added carbon. I was able to add fish a week later, after a big water change, and lots of skimming. Corals were fine and no other problems. So the moral of the story is, don't let them get sucked into pumps. I still keep cucumbers(nothing better for your sandbed), just have intake guards for my return, and skimmer pump.

As Mike noted and as explained to me the other day by a friend, a cuke will generally only release it's toxins if it is extremely/traumatically stressed. A cuke that starves to death will not, and often even a cuke that dies of other causes in aquaria will not, as they will use available resources first to simply survive (ie. continue cell production) and if those needs are fulfilled, they will begin worrying about defenses, ie. toxicity. Similar to the psychologist Abraham Maslow's Pyramid of Needs - survival needs (food, water) come before defense needs (shelter, spears, sniper rifles).
