One thing that I've noticed from running a tank maintenance company is that the corals in the tanks lit with LEDs are more finicky. The T5 lit tanks are just "easier" to make corals happy. There are so many variables, but I can definitely say that for some reason LEDs make it so you have a smaller margin of error, and some corals just don't thrive under LEDs. All my T5 lit tanks I can put pretty much any coral in the tank in an appropriate placing and it will thrive.

Having said that, I find in particular, the LPS corals that we're getting these days compared to 8 or 10 years ago need far less light than they used to. I think this is probably from collectors having to dive deeper these days and the corals originating from deeper depths and less light. For LPS tanks, I like to run all blue bulbs (like Blue Plus, not all actinic lol). LPS really need very little light to thrive. My own SPS tank has 6 T5 bulbs and 3 are white, 2 are blue, and 1 is actinic.
