Cucumber

[mnoll406]

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.
