Female Platy Becoming Aggressive

[Daveo026]

Hi all just got in from work and one of my female platys is being very aggressive it's pecking at the female dwarf gourami til she hides and the platy has just attacked my male dwarf gourami resulting in a small fight is this normal??

never heard of a platy doing that.. check your water stats and separate her..

 

[Daveo026]

She's separated now
0 ammonia
0 nitrite
20+ nitrate

So nothing wrong with water and I did a water change 2 days ago and il be doing another one later

 

[BerryAttack]

usually its best to keep them in groups of 3+ ... so you can always return her or get two more and see if that works.

I have 4 females only this one has started showing aggression today
