Swordtail males' aggression
Now, I've noticed that in the pet stores, multiple males share tanks without any problems. I don't see them chasing each other.
I already have a single male orange swordtail in my pond. Yesterday while going around, I saw some beautiful kohaku pattern (orange and white) swordtails and I bought a male. After introducing him to the pond, the resident swordtail chased him, with occassional nipping. However, the chasing isn't that persistent, since the chaser usually lets up and finds something else to do.
Will the chasing stop when the two guys get used to each other? I think that is the case in the pet stores. Or do male swordtails need to be from the same brood and be together for life to prevent fighting? Oh, and I don't have any female swordtails in my pond, only female mollies and the swordtails pay no attention to them.
