I ripped mine in half trying to remove it from the DT. It was stuck to two rocks. I have two now that live in my fuge , been there for like 6 months. I don't have any good(safe) ideas. I actually didn't care what happened to mine, it was huge and stinging a lot of different things, and if I change something in the tank the darn thing would move and create a path of death. So, now I have 2, go figure. They will end up in a 29 that I plan on setting up soon. Sorry, not really helpful.
