anybody know why 2 of my 3 balloon mollies would have it in for the 3rd molly? my black female and white male have decided that they no longer want to get along with my orange female. when she gets close to them they both dart at her and bang off of her sides and appear to be trying to nip her as well. she seems undetered and continues to try to stay near them, only to always be chased off again. would adding another female balloon molly add to the chaos or help alleviate it? please help!

hello, i was just curious to whether anybody knows if powder blue dwarf gourami's come as females, or if it's impossible for one of this color to be female. i've only ever seen males, and i can't seem to find any real info on females or where to get them. if anybody knows where to find them in Massachusetts, or rather, if they even exist on this planet at all, please let me know. it would be very much appreciated.
