The girl that was causing the problems... was it the one in the cup in the first pic, and flaring in the second and third pics? Because I think I see a beard, and if I recall correctly, that could mean that "she" is a he... And that would explain the aggression that you're seeing. Anybody else see this?
No those are different fish. The one flaring in the second picture is the aggressive one but she is flaring up her gills too. There are 2 other girls who do it too. They look normal otherwise. She is also the one in the picture that I posted last night.. The one with the female sleeping on the leaf.
So far everyone is getting along.. There is a lot of chasing going on which is normal, but Princess and Fiery seem to only go after the bluer colored females which are the ones that are 2 of the 3 crown tailed. They don't pay Lady any mind which confuses me.
Princess and Fiery have the closest bodies to males out of them all.
The top picture in the line up I just posted is of Fiery, she is the one giving me the most trouble. Princess isn't as bad but she gives a little bit of a chase after the blue ones too.. Give me a second to find a closer picture of Princess
