My son recently bought a pacman frog from petco. We have followed all of the rules we found on the internet. I have some questions that I can't find answers for. We feed him crickets mostly. My daughter decided to give Pacman a friend and put an ordinary wild caught tree frog in the tank with him. Yes I know the risks of pesticides and such. The tree frog didnt last ten seconds. After a month Pacman never showed signs of distress or anything so we gave him another. He LOVES them. Is this ok? Are regular yard toads, lizards, caterpillars, or beetles ok? Not every day but a time or two a month? What other kinds of critters can I give him? What things are an absolute NO NO or poisonous to him? For the record, the tree frogs were caught in the middle of the woods. No chemicals any where near. Thanks for the info in advance.
