Child takes iPhone's 'Tap Fish' bait, reels in $600-plus bill

Tap Fish, an iPhone app that simulates caring for fish in a tank, is a lot less popular in many households across the country as parents discover hundreds of dollars in charges to their iTunes accounts.

The story is becoming increasingly familiar: A kid plays a cute game on their parent's iPhone and decides to get some more play money for the game. The only thing is, game money costs real money.

That's something a Florida father recently learned.

Frank Mendez told a local NBC affiliate that he downloaded the free Tap Fish iPhone application for his 7-year-old to play with. The aquarium game allows kids to clean the tank, feed the fish and more. What Mendez didn't realize is that the free app also includes "in-app purchases," which allows users to purchase fish and other virtual items.
