Hi Grif: Do you or do you know of anyone with personal experience of raising a pacman on only the dry food? I'd just like to know how the frog was, and the long term results of the food. That last part would be a challenge. I think you would have to do a necropsy on the frog. And, to do it correctly, you would want analyze several frogs in order to get a representative sample. However, if the frog lives 10+ years on only pacman food, I'd say it's a success.
As far as the expense.....I had an earlier post looking at nightcrawlers. Of course it assumed several key variables....I'm a supervisor in a steelmill with a six sigma black belt, so I spend a majority of my time statistically analyzing processes. And looking at the cost of various foods would be interesting. Now the issue becomes which food is most effective? It's almost beyond the scope of what we're discussing, but it needs to be, at the least, acknowledged. I posted this question on another forum and a couple of the replies were very negative. "They don't eat it in the wild" those types of comments. So I didn't think I would get an objective reply and came over to this site....Much more open minded.
Anyway, my plan is to bring in some nightcrawlers and crickets to work, weigh them on our scale in the lab. With accurate weights, and hopefully I can find some analysis of the the feeders, I can determine exactly how expensive each item is.
Yes, a varied diet just intuitively sounds better. I read a little about people feeding hornworms......Have you ever used them? If so, what's your opinion.

Thanks
Lloyd
