I'm not sure what type of plant that it is. I would agree with frogzilla though in that it looks like the type of plant that would need to be separated rather than take a cutting.Looks like a peace lily to me. If it is you would have to separate it rather than trying to take a cutting. It would do great in a vivarium as they can grow semi-aquatic and love water. On the other hand it would get HUGE in a vivarium, I wouldn't put it in anything less than like 24" tall.
