ive him some veggies. they love peas-no skins, blanched romaine,watermelon,garlic,cooked red peppers-no skin,broccoli,chard,zucchini,cucumbers... honestly the list goes on.i'd feed mine beets if it wouldn't turn them purple. these things need to be bite size obviously. new life science is my pellet food of choice as the ingredients contain 14 fruits and vegetables along with b12,niacin,folic acid and a bunch of other good stuff. your minnows would benefit also. it is a bit spendy at about 10$ for5.3 oz (150g) but very worth it.imo. they gettin along better?
