I realize now that this photo might not be so funky to some fish enthousiasts, but to me it is very special and I wanted to share it with you all because it turned out this way by accident.
The tank is actually quite bare with a few small plastic plants, and after taking the photo with a different flash effect, and seeing the reflections of similar blue colours to my betta, and the beautiful mirror effect of the water surface, I felt that the camera added more beauty and mystery than there has ever been in reality.
