Has anyone had a sea cucumber crash their tank?

After reading these posts, I guess it is not worth the risk of my whole tank for one of these guys. I guess he can go into my quarentine tank until I can see if the store will take him back. Thanks for the info.

Is it tiger tail cucumber safer?
I bought one a couple months ago; it is cleaning up my tank nicely. But this infor. thread makes me scared.
I really need advise, specially from someone whose tank was crashed by it.
Thanks

I've kept tiger tail cucs for years, with no crashs (again, furiously knocking on wood).

I had one a few years back, I don't know what kind it was but is was black. It disappeared and I never noticed. Guess it died but nothing was affected.

I've kept tigertails for years without a problem other then they would slowly move the sand from the front of my tank to the back. They are one of my favorite sand sifters and I will probably always have one or more. From what I understand the pink filter feeding ones can be quite toxic and can release toxins when stressed or threatend like if the get caught in a powerhead. They seem to like being in higher flow areas to feed and that often means near a powerhead. They also usually slowly starve in a tank because there isn't enough food for them. The tigertails live on the bottom so that is never a problem.
