A Real Fish Enters the 'Shark Tank'

Published

It's always risky business for participants stepping into the Shark Tank in a bid to convince the panel to invest in their products.  In a sneak peek of this week's episode, a colorful lionfish becomes the focus for company hopefuls seeking big bucks for their seafood business.

Watch the clip to see whether the panel -- which includes billionaire Mark Cuban, inventor Lori Greiner, real estate mogul Barbara Corcoran, fashion and branding expert Daymond John and venture capitalist Kevin O'Leary -- will respond to the pitch of Traditional Fisheries, an eco-friendly company harvesting lionfish for food.

You can catch the full all-new episode of Shark Tank tomorrow night at 9 on ABC.
