So after my son impulse bought this little guy a few months ago, I was reading up and am wondering what everyone's experience has been with them. It started as a 2 inch cutie and is now around 6 inches in length sharing the tank with a giraffe cat, 2 Oscar's, and an aro. How big has everyone gotten them? How nasty are they really? And how big have they gotten? I'm getting conflicting information as to final size. Some say 18", some say 30"+. Doesn't matter size wise. I have the ability to house it in the pond. Temperament is the issue. Currently the boss is a 3 foot hybrid who is not the nicest but pretty much leaves the rtc alone.
