I have been growing out two giant African bullfrogs. They have grown rapidly mostly on dubias,earthworms ,tadpoles,cooked shrimp,rodents,imitation crab legs,minnows. They are doing great so far. But to many rodents is no good for the frogs. Its an easy way to fat them up and that is not normal. But I'm glad you are keeping records on your frog. Its very smart.You can actually catch something wrong sooner then late.
