Someone else asked this question last week I think and this what was told to him from people that are very experienced with pacmans and have owned them for years. This can be very harmfull and dangerous to your frogs health if not done 100% correct. This is why there is not alot of horned frog breeders out there. To be honest if you are not a pro at this frogging thing and have to ask these questions please do not try this because you or the person doing it is just going to hurt the frogs
