Are Sea Cucumbers right for your tank?

How large do they get before they split? This one has put on a good size. I only get to see it some nights after lights out.

mine when stretched out was about 7-8" easily before the split. Not that I had option, but I like them smaller. Having two 3-4" now. Like someone bought me another vacuum for my sandbed.

WARNING - I'm sitting here watching most of my fish die in my 180gallon from the cucumbers in the post above. I've always heard they are ticking timebombs, but I didn't believe it. Considering I've had them for many year and even split which was fascinating, but poisoning your tank is not worth it.

Few hours ago, I saw my corals closed and fish are hiding. I knew something was wrong because these are 7-10 year old large fish which I know their personalities and their activity levels. I knew something was wrong. I saw a piece of flesh fly by which had the pink which immediately looks like my 2 cucumbers, but then the 2 cucs walking around just fine. ... so where did that piece come from? Did I have another split that made it to the sump and eventually went through the return pump? (That's the working theory).

I'm running aggressive carbon through a reactor. 3 confirmed deaths and what's sad is the larger older fish. I can't water change fast enough to make an impact in a large system so I can only hope to clean the water. I'll take the body count in the morning but I will be taking those cucs out. Don't do it. It will happen one day.
