Help! Male gudgeon was very aggressive towards female!

I was watching my two gudgeons a moment ago when all of a sudden my male flared up a bit and then the female.. I know its a female cause of the head shape... Her head is very flat and she has black on all her fins besides the tail... But they literally started to teleport it looked like cause of how fast they were! They were both flaring really hard at each other but they were not chasing... They just kept going around eachother... Ive never seen them do this... And for a male to act like that towards the female? Weird...

Sorry for the blur but this is them now... Their really chill like nithing happened... They just swim next to eachother peacefully normally... Maybe they just got into an argument? Lol

A lover's tiff, she must have said " Not today I've got a headache" and he got annoyed, he will go down the other end of the tank and sulk soon.
