Good addition to a CUC, but can release a powerful toxin when stressed

I had one of those at one point and read some bad stuff about their toxins and threw it out. Didn't want to chance a tank wipeout

They're very easy to maintain, no need to throw away.

Thanks for all the responses. I did end up tossing it. I looked up the references that were made at the top and came across a couple that talked about toxins. Im not willing to go down that road. I m still working through the after effects of treating black bugs. Bugs are gone but coral growth has slowed and alk started to rise. Still waiting on stablility testing alk every 12 hours and adjusting doser past few days have been add and subtract and back and forth.
Anyway thanks now i know.
