I think Massivore is way overpriced. Can you get Xtreme? My fish eat it just as well, for half the price. You would need to get their Monster size pellets. I understand a lot of breeders use it. I currently mix mine with half Massivore but may start just using it as a treat or to get hard to feed guys off of live. Can you order foods from the US? I bought stuff from Mexico and had it shipped through the mail with no problems.
