Came home tonight to find my male clown dead

Looks like there was a big panic in the tank,frags nocked over and he was on the intake screen for one of the power heads.Now she just circles around searching for her mate,its really heart breaking.
They were togather for nearly 3 years,so I don't know if I should get another to take the male's place or just leave her?Will she accept another clown(false clown)?
