Hey all, i have a 20h aquarium with a trio of apistogramma agassizii fire gold one female is extremely dominant and i have one female being picked on. the male has stopped chasing the dominant female and kind of swims after the less dominate female on occasion. They are in a tank with one bristlenose pleco and 2 guppies that are old and have scoliosis, they act as dithers. What should i do? separate the females, return one?
