Well thats funny. MY lung began to eat almost right out of the gate. I think fwlion is just mad cause my lung is larger and more peronable than his. We purchased these lungs at the same time,and have been offering a varity of food items. Spirulina pellets,Salmon pellets, Mas pellets,nightcrawlers(which Fwlion wont cut up)Tilapia and Krill. Our Beast eat well. But right now mine shines brightest. Iwill post sum pics. u be the judge.
