Thank you so much for you reply, I appreciate that! When It comes to backlighting, it's normal to use some type of hazy and week backlight together with a transparent sticker or plastic screen to make a misty/hazy and light background. This usually fits well with the composition of the Aquascape. Other times the back of the aquarium is colored black or a dark blue color so backlight is useless. But for camera purposes the strong light you need to keep the plants in the tank happy is more than enough to get a bright and sharp image. I hope this somewhat answered your question.
