I have 3 mollies, 2 female, 1 male. Used to have 6 but 3 died Anyway the 2 remaining females don't seem to get along, the orange one is always chasing the dalmation, she is especially jealous if the male has a sniff. Is this normal? I am planning on getting more, another 2 females and another male, once I'm sure that I've eradicated whatever it was that killed the others. She wasn't so much of a bully when there was more of them.
