J.T. Realmuto broke the Marlins Park fish tank's protective glass behind home plate

Something fishy was going on in the first inning of Friday night's game between the D-backs and Marlins at Marlins Park.
Miami catcher J.T. Realmuto hit a foul ball off Arizona lefty Patrick Corbin that struck the fish tank stationed behind home plate. A small crack emerged in the shatter-proof glass and water began spilling out.

Don't worry -- the fish are fine! The issue was quickly resolved, and the fish didn't even seem that bothered.
But Marlins president David Samson did joke with MLB.com: "After the game, we're placing two fish on the disabled list and we're calling up two other fish from the Minors."
The two large fish tanks on the walling behind home plate are among the most popular features at Marlins Park. Flanking each side are two 450-gallon tanks that house a number of colorful tropical fish. They are protected by shatter-proof glass. Realmuto did his best, though.
"When I looked back, there was glass all over the dirt," Realmuto said. "I was just waiting for the thing to explode and fish to start flying out of it. Luckily, that didn't happen. They were wanting to play through. I was like, 'Hey, you might want to get that glass off the dirt back there. I don't think the umpire saw it. It was pretty crazy." 
What happened on Friday night, however, was a first. Never in the history of the park have the tanks being damaged.
But in the first inning, Realmuto fouled a pitch off in such a way that it compromised the tank.
"The ball had an angle we had never seen before," Samson said.
