ive looked int0 the powders awhile ago. it has only really been available recently and people have been hating on it but i think its good for those who dont like live bugs, worms, mice etc either handling and/or feeding them to the frog. also no other supplements are needed when giving the powder to pacs. all nutrients and calcuim is provided. the problem i heard from one guy who bought a samurai pac and the powder food is that the pac didnt go for it. i think the powder food is a safer route when you take parasites and other nasty stuff into account that live feeder food could transmit to your frog.
