I am a beginner into this world of aquarium. I have got 2 gouramis one is bigger than the other. It has been 2 days since I got this new aquarium. First day bigger one was chasing the smaller one. I thought they were playing but today I observed that the smaller one has turned bluish from white and she is hiding from the bigger one. The bigger one is constantly chasing her. Both are females so I don't think there is a mating issue. I am too worried about the smaller one. Please help!! I am hereby enclosing a picture of the color change in my white gourami.
