Hello, I have had a 70L freshwater tropical aquarium for over 5 years now and, I was just wondering If I can change my regular fluorescent light for a new blue fluorescent light. I just want to change my aquarium, its only for decorative purposses!

Questions:

- I only see Salt water Aquariums with blue lighting... does it harm freshwater organisms in any way? Or is regular lighting just better for freshwater aquariums?

- Do these blue lights use more electricity?

Infofmation:
- I just have plastic plants (no real plants), so the blue light as I mentioned before, is only for decorative purposses!

Any useful tip will be much appreciated!
Thanks!

If the light is just colored blue, it won't hurt the fish. If it's something like a uv light or something, then I'm pretty sure that unless the fish need it, I wouldn't use it. I'm not sure if they use more electricity, but you can check the watts and compare to your current light.

Hope this helps.
