Clownfish pairing aggression

I just got a pair of clarkii clownfish I'm wondering the female wont let him in the anemone except for at nite the sleep in it.. She chases it around but he has minor rips ... Not bad ... But he will twitch and stuff he's about 2 cm smaller not a big difference iknow it's bad but still ... The pics are of the female share them I'm proud of them!!!! I want them on google! Will she and the male turn black as they mature ... It's a 29 gallon biocube I just got them yesterday thanks !
