Im pretty sure alot of the pacman frogs in circulation are coming from the frog ranch.
While I didn't have ANY problems with any of my pacman frogs over ten years ago, the last three green pacman frogs I've had refused to eat. The one I purchased from a petco years ago rarely ate and grew slow, which was a big let down because well, theres a certain appeal to pacman frogs and its all in the name. I had him for a year and he never grew to more than 2.5 inches. I have two green ones now that behave in the same way, and also had red rear thighs from the time I purchased them. I've been force feeding, gently, the whole time and have recently begun administering antibiotics. Since the antibiotic treatment has begun they have began croaking and their color is brighter and more vivid, and their thighs dont have reddish coloration or visible capillarys. Im not sure if they will start taking food yet or not.
I'd like to see hobbyist level breeders begin to take a bit stronger place in the market and give big commercial operations that produce so many unhealthy frogs a run for their money. It probably doesnt help when the Frog Rqanch suggests that the frogs can be maintained in the coir filled deli cups they are shipped in for several weeks.
