I've seen some amazing green and even a golden versions of the phantom, but I personally own a blue. I actually disagree slightly with the previous comment. It's definitely a strong fish that throws around its weight when it wants something but it's never gotten aggressive with any of my fish; all of which are community and would be easily bullied with the exception of the black ghost knife. It shares the tank happily with my common pleco of identical size and is actually less active. I've actually seen it on my rope fish; which originally caused the rope to panic and swim away quickly kicking up sand but now that they have been together awhile, the blue phanton actually appears to clean the rope fish's body! It just lays there as the phantom goes down his back, and I've seen this process a good dozen times. My advice; with a big enough tank, ample rock caves setup, daily periods with the lights off, and proper tankmates I don't think you'd have an issue. He's even been coexisting with my 3 lobsters that he's a good inch bigger than.
