well how old is the cham ?? n is it a male or female? If you have a baby they will eat alot. And if you have a female and she is reaching maturity u need to slow down her feeding. And if u have a mature male u dont want him to get chubby so be careful don't just keep feeding... And u should be feeding more than just crickets.. mix it up, horn worms, butter worms, maybe some roaches good luck with ur new cham.
