Ocellaris Clownfish fighting all of the sudden

[djk1]

I have a 55 gallon reef tank with 2 Ocellaris Clownfish(tank raised) and a sunk clown along with 2 tangs 4 chromis. The clowns were one of the first fish in the tank thats 5 months old now. All of the sudden last week the bigger of the two clowns started getting very aggresive with the smaller clown. Is this normal or is there a problem? What could i do about it

i had two ocelaris in my nano and i had the same problem...
i would say : or the larger one ( female) don't accept the smaller one sa her male.
Or the smaller one is trying to get dominant/ female, so the bigger one fights it...

same thing happens in my tank but after they nip at eachother the smaller one starts twiching for a second or two then swims away its pretty weird !

so this is normal or will one die off? Because the smaller (hunted) one found a hidding spot and does not move from there
