Well, I can tell you that TileFish are generally not that hardy and this one isn't very hardy at all. Cool little fish but they aren't good to have in an aggressive tank. They are rather peaceful but they basically need a species tank because they eat corals, which means they can't be in a reef tank. They also are small, slow-swimming fish which have a peaceful disposition which means they can't be in an aggressive tank. They need to be with other small, slow-swimming fish such as Boxfish, clowns, and other small peaceful fish. If you plan on getting anything but a tank made for them then I would not recommend these fish. Again, they aren't hardy and seem to be quite supcepptible to diseases, most commonly ich. They also are very shy and sometimes die from starvation. I've looked into one in the past, but I don't want to have to make a tank that is based on this one fish.
