Old post but im interested on this line. Is there any conclusion here?. After some months of trying to get my MM started to eat Hikari Massivore as his main diet he finally get them as his favorite, and yes, his color has changed but he keeps in good shape. Im thinking about include some other brands of pellets in his diet like NLS Thera A+ Jumbo, and he´s currently eating the Ocean Nutrition pellets for bottom dwellers (normal and w/spirulina) very well. I think that there is no problem with let him with pellets diet only if the diet includes a wide variety of components. Im also about to buy the Mazuri Gel cause he eats very well the Ocean Nutrition Shark Formula wich is also part of main his diet.
What do you think????....
