He eats fish (he's a picky bugger), he likes salmon etc (which I add vitamin to frequently (for the whole thiamine vitamin thing)

He also likes earthworms hopefully I can get him some,

he just never switched, he loves live fish but they are pricey.

Since my female orochi became gravid I've been working on getting my guppies to bred as food supply if needed, he loves guppies when I can bear to give him one.
