Today/Yesterday was the last air of the anime (as we know, that is) They're putting it on hiatus since the anime is far too fast and the manga isn't developing fast enough for them to constantly release a new episode each week.

Mashima did mention on his twitter that "The anime is not over", so they left it open. I do believe that it will pick up again during April, though.
