Mmm I can see this getting long winded .When you state "PacMan Food" are you referring to this product from Japan: =TOP= of PacmanFood.com . I've never used it; but did feed my African Bullfrog and Pacman a product from Repashy available at local Pet Shop called Meat Pie: Repashy Superfoods :: RETAIL SALES :: By Product Name :: Meat Pie Reptile Gel :: Meat Pie Reptile 4 oz BAG - Repashy Ventures - Distributor Center. I have no way to make comparisons; but both my frogs ate it and I gave it to them as a supplement to their dusted night crawlers main diet (2X a week CA and 1X a week multivitamins, both from Repashy).

Although your sample size is only one, it's a marked growth difference between it and the other frogs. If you take the three smaller frogs and feed one dusted night crawlers; PacMan food to second and either dusted crickets or Repashy's Meat Pie to third it would make and interesting comparison. In my humble opinion earthworms are the "perfect" live African Bullfrog & PacMan food.

Japan does appear to have stricter quality control and regulations (and I use Hikari foods for my fish). Having said that; my past experience with pet foods coming from other Asian localities (Malaysia, Thailand, Taiwan, China) is one of apprehension and doubt. It's very hard to know what you are exactly feeding your pet (hormones, etc.?) and even when you find a good product; then there are the clones coming from China and only God knows what is inside the look alike bag. Remember the fiasco couple years back when a Chinese company was discovered adding pulverized plastic to dog and cat food in order to raise the protein content ?

I would be very observant of a product that affects growth that much. Not only is there a possibility of growth enhancing compounds in the mix; but the accelerated growth itself might create a challenge for the organism and lead to permanent issues. Our bodies and those of all living creatures have genetic triggers that respond to many inputs including chemical and hormonal levels. Start messing with those and you affect the whole system. As an example; it's my experience that the process called "Pumping" in fish raising is negative to the fish. They might grow twice as fast... but their bones are not as strong and apparently internal organs growth is challenged too. I have a local friend that keeps, breeds, and sells tarantulas. There is also a process to make them grow fast by raising temperature and overfeeding them. When he tried to do that with his males; he eventually lost them during molts before he had a chance to breed them... just saying.

I can see a benefit in using PacMan food to a breeder that wants to bring froglets to market size as fast as possible. Still; for the hobbyist with one to few PacMans, providing a balanced diet to include live items might be a better way than to use a single prepared food that makes them grow very fast. I'm looking forward to your test results and other comments of users, specially breeders. Good luck !
