How LED Light Affect Fish and Corals in Your Tank will Look?

I always say that you only really need three thing s to be successful in this hobby, good water quality, good water flow, and good light.

All of those things are pretty involved but lighting in particular gets a lot of discussion, because of the three it is the most exoensive and the thing that is going to most dramatically affect how the fish and corals in your tank will look.
My goal in making this video isn't so much to give a prime to beginners, it is to illustrate just what a difference lighting can make. Corals can color up differently under different lighting systems to varying degrees, but lighting systems can also drastically affect the appearance of the same exact coral. A lot is made of what corals look like online. Are the images oversaturated? What kind of lighting was this taken under? The list of questions go on and on. What most people do not realize is that much of what that coral will look like has more to do with the lighting selection by the hobbyist than the image of the coral online. Obviously there are pictures online that look way off, but assuming for a moment that the picture is good, there is a really good chance any coral is going to look very different from tank to tank dependent on the light.


I try to show the corals on my site and during the live shows under different types of lighting, but these things are just helpful guidelines at best. In the background you are seeing some corals illuminated under different types of T5 bulbs. Moving from T5 to a different technology altogether such as LED or MH will have an even more pronounced difference. In the clip I just showed, I transitioned from a full actinic look to an almost full daylight look by changing lights. Go back and take a look if you didn't notice the first time around. Here you can see three slices of the same coral under those different lights. One might think that the solution to this is to only shop in person for corals. I try to do that as much as possible. I have purchased corals in person that looked spectacular. One in particular looked really special. It was glowing red and yellow. The yellow in particular drew my eyes right to it and I decided to purchase it. An hour later when it was in my tank it was...nothing. The res wasn't really much more than a tan color and the yellow was maybe a slightly different tan color? Had I purchased this coral online sight unseen, I might hava been disappointed with what I received, but that wasn't the case here. I bought this piece in person!

Ok, so what's my point with all this?

My point is while there is no sure way to pick out corals you do have a great deal of control over what it will look like regardless. It almost looks like three different corals altogether, but it is really just lighting at work here. I hope you guys liked the video. In the comments below, let me know if you want a deeper dive into the topic of lighting. Thanks again!
