Hi guys just watching my fish and i have got two fighting .Im not sure if they are pairing up or not ,first i put a new fish in a tank with a pair (male pidgeon blood/female golden crystal) and 3 sub adults the new fish is a red turk/brown .At first the brown hide after a few days it was out fighting for food ,now it and the pidgeon seem to be fighting they lock mouths and push and pull .They also size each other up next to each other and slap with heads and tails. What do you think ?

just sorting out who's boss. if the tanks big enough they'll establish themselves a teritory, if it gets REALLY bad you might have to move the more aggressive one out.
