yeah np and you dont have to necessarily feed live for them to go after them, i have never fed my gold dempseys live food, and i just added a small geo i was growing out to the tank and the female is still trying to go after him, and she is not even big enough to eat him outright, she is about 4.5in and he is 2in or so, and thats a geo, granted its probably because he is hanging out at the top acting like prey but yeah just to give you an idea about the predatory nature of the cichlids we keep, they will naturally go after a fish they deem small enough whether ever fed live food or not, but danios are pretty fast so hopefully will be ok
