That would probably be the result of using LED lighting. Video will make this more obvious.

It looks like it has some natural color variation in the yellows/greens/teals but theres also a bunch of separate LED colors refracting through the water. Looks cool on that particular coral but its also happening on the surrounding rocks. If there is a lot of water movement this color dancing can get really distracting.
