Hi all, i have 2 agassizi's which i believed to be male and female, however i am now having doubts. My male is a certainty...hes twice as big extremely colourfull and his fins are out of this world!! My female shows all the signs of being female (smaller, less colourfull and a rounded tail as apposed the his pointy tail) i have had them about 3 months and am slowly lowering the p.h to there preferances. Over the last month my male has become aggressive with the female. If he sees her he will flare up and charge full speed at her and occasionally if caught will nip her in the side. Other times it seems as tho he goes hunting for her. He randomly flares up and goes looking and if he spots her will charge at her. There not as bad when its feeding time but if she gets too close he chases her away. What i dont get is when i 1st bought them they were inseparable...any help would be a hugely appreciated!
