Saltwater Aquarium/Devoid of Natural Sunlight



My question is that in case of any aquarium wether freshwater or saltwater, the fish that reside are devoid of natural sunshine. I mean that I once saw a program in which a monkey was shown. The monkey was kept inside all it's life and so it's skin was pale. So in case of a fish, can fluorescent bulbs or any other lighting take place of the natural sunshine?

Hi Jem:

While nothing can ever reproduce the suns natural rays, years of studies, evidence, and home aquarium enthusiasts have all shown that by using full spectrum Metal Halide lighting, Power Compact or Compact Fluorescent lighting, Incandescent lighting, and LED lighting one can successfully keep fish, including: aquatic zoos, public aquariums and aquarium hobbyists abroad can successfully keep fish in captivity.

There is a plethora of information in regard to this subject online. Just do a Google search on the subject and you'll see hoards of information pertaining to this.

Thank you for the question.

I possess over twenty-five years of hands-on experience and knowledge in the ecology of aquariums. Beyond the traditional, I have successfully tested and sustained environments that have been uncharted territories for hobbyists, for decades. I am the first to admit I don't know it all because there will always be something new, amazing, and exciting to learn about, as discoveries are made. It's a hobby one can never outgrow, or grow tired of.

After High School, my experience and love of marine animals influenced me to take up studies in Marine Biology. Throughout college, I studied Microbiology with an emphasis on Marine Life, as well as numerous other sciences. I continued to advance in this hobby, by building a dozen or more saltwater ecosystems all utilizing Microbes as the major source of my filtration method.
