if i found hairless mice i'd feed those. i never feed mice due to the fact that it is messy as hell. usually i feed anything honestly. any kind of pellet, any kind of meat, any size shrimp. there garbage disposals.
my piranhas eat veggies , cichlid pellets just for color enhancment, lots of large feeders i breed my own but i have been doing it since i had my oscars long time now. but now i see alot of u guys are breeding con's for feeders might have to try it . but they seem to like veggies i just take cuccumber and thinks like that and stick sinking pellets in them they seem to like.
