well i didn't have everything to use the recipes on this site, but i made up one of my own using krill shrimp, salmon, carrots, peach nectar, romaine lettuce, sweet potatoes, and pears. put it in a blender till it was a paste, froze it over night then cut it into small squares. taco (albino tiger oscar) loves them, but paco (red oscar) will not touch them as soon as it hits his tank he takes a small exploratory taste, spits it out and wont come near it again. I'm going to go shopping for a couple of the recipes from on here, gonna go without feeding him for a few days and see if he will eat it then. if this don't work i don't know how I'm gonna get veggies into his diet.
