I got mine to eat worms and white market shrimp first. Try soaking Hikari Massivore Pellets with the shrimp in the shovelnose's own aquarium water. Depending on fish size , you may have to break up the pellets with a knife or razor blade , that way they won't crumble. You can also hide pellets inside of the frozen food it has already taken. They get the taste of the pellets somewhat that way also.
