Ok i have two gourmais one died last week from being bullied and starving himself. The two i have left are blue paradise gourmais... most of the time they get along but there are times when one is chasing the other. Today i was watching them and noticed the aggresive one puffing out his gills like a cobra does... he would flare them out and the other fish would back up but if he came close they would flare up again, is this a sign of dominance and aggression or could it be signs of sickness?
