Mine are very habitual. Hide in the same spots, one spot happens to be in a highly visible end of my tank. They come out like clockwork, to the surface during feeding time. Like I've mentioned to you, the food is isolated in the top right far corner of my tank. I find any tankmates too large to be swallowed and nonaggressive to be good tankmates. Burmese archerfish, large barbs, etc. Check out my old videos on this thread.
