Hi. I am relatively new to this aquarium world and is interested in breeding mollies. I have a big size female black molly and a medium size male gold molly. I have read about 2 or 3 females to 1 male ratio and added 1 small size dalmation female molly. But it was fin nipped and harrassed by the big black female molly and died. Currently the gold male constantly chases around the black female and once while changing water I kept them in a small bucket and harrassed by the male the female jumped out. Luckily I was there and gently put her back. I have provided a hiding place but have not separated them yet. I want to add another female molly but cannot decide. Should I get another big black female molly or a medium gold female molly?? If I get a big black female will the big black females kill my medium gold male?
