Female guppy attacking male platy

[Ellio]

Hello!

We've got a bit of a odd one. One of our female guppies is randomly attacking our male Mickey mouse platy.

The name told onto his side next to her and she pecks at his side for a bit and then he swims off and chases one of our other male platys.

What should be causing this?

Tank mates are;
7 khuli loaches,
1 Bristlenose pleco,
3 female mollies,
2 other male platys,
2 other female guppies.

Thanks very much!
