Btw, gorgeous fish! I'm a fish nut myself, and have a soft spot for venomous fish. Sadly, I don't have the room anymore to keep a separate tank for them. Hopefully, in the near future I will once again have space. I would love to set up a tank with a Rhino, an Ambon, and perhaps even a devil fish.
They are very pet-like fish. Please keep us updated over the next few years. The Rhino longevity accounts definitely interest me.
