Lyretail Mollies

[DyArianna]

I have a question on the general temperament of Lyretail Mollies vs other types of Mollies. Do Lyretails seem to be more of a bully or territorial? The reason I ask is because I only have 2 bullies out of my six Mollies (1 adult and one juvenile), both female. The Sailfins are just fine! The bully fry is the offspring of the adult bully....but the sibling fry (not lyretail) is not q bully at all. There are only 2 adults, the rest fry....20 gallon. Water parameters via API master test kit are 0, 0, 20. Water is slightly brackish and I do 25 to 30% water change weekly. And I do dechlorinate and temperature match water going back in. Any thoughts? Thank you in advance for your time.
