Just wondering , on a hefty feeding schedule, once a day, but highly varied, what can be expected from say maybe 1-2" in a year? Do they show a preference/benefit to favorite foods? Are they always psychotic or can you mix them early-on and establish a tank with them and other equally nasty fish? How soon can they be sexed and what is the best way? I imagine females are much more likely to "get along" with other fish, anyone have experiences of success they want to share which species with? I have been told growth is fast, at what point does the growth rate start to slow? At what point does Pinhead and the Cenobites jump out of them and rip you apart with hooks on chains?
