Tank

What Tank may lack in eloquence, he makes up for in strength and a huge heart. He's the oldest and biggest and the engine of our fish trio. Helping a baby jellyfish? Not a problem for Tank. Riding the biggest and craziest currents in the ocean? Bring it on! No adventure's too big for him. Dorsel and Bubbles let him often take the lead, and they know that though he may be gruff and buff, he's a big softie at heart.
