Aggressive Female Kribensis

[Guppi32011]

Hi all, bought 3 kribensis yesterday, 1 male and 2 female. Both of my females have large red/pink bellies. My one female who is more pink than the other female has gotten quite aggressive to nearly everything in the tank. The male and the other female krib are peaceful with each other. Why has my one female got so aggressive? Is it breeding time??

It could very well be. I found my female kribs were the aggressor when it came to breeding time. She may be staking out a spawning territory.
