Identify Bolivian rams

[LJS1995]

I’m new to Bolivian rams I was wondering if anybody could help me please firstly on the sex of each one. The fist one which is smaller is supposed to be male and the other which is bigger (hanging around the seahorse) is supposed to be female. Also on the behaviour of them, the “male” keeps approaching the “female” but she chases him away but yesterday it was the other way round she was approaching him and he was swimming away from her.
