I thought she was a regular molly for the longest time but she is like 1.5 times the size of a full grown molly. Figured out she wasn't from another thread but idk if she is a female swordtail or sailfin molly. I had a look and there is something about the position of the mouth and colourings but I am still super confused . I really wanna know so I can get her friends so she stops picking on my new mollies. She didn't seem to mind her old molly tankmates (they got hit with velvet the most evil thing) but hates these new guys. Glad she doesn't care about my precious catfish at least. I will try asking my local fish store to.
