Texas is reminding folks that keeping piranhas as pets is a no-no. The warning this week comes after a 5-year-old girl on her first fishing expedition hooked a red-bellied piranha at a lake near Houston. Lindsay Schutte used a hot dog to lure her unique prize. "When I took the hook out of the mouth and saw it had pretty big teeth I was concerned, but I'm in Texas so I don't know, there could be fish like that," Christi Schutte, Lindsay's mom and a recent transplant from California, told NBC affiliate KPRC-TV. But when the fish bit Lindsay's brother, the family decided to notify the Texas Parks and Wildlife Department, which killed the fish and then froze it for further study.
