I had 5 swordtails. 1 male, 4 females. But the females all died due to stress and fungus. My male is just sitting at the back of the tank behind the heater where you can barely see him and he won't move at all unless he's forced to move with a net. He looks perfectly normal, but he'll only come out to eat.
Is he sick or is he mourning for his 4 wives? lol... Is he just sad or sick?
