Anyone know of any bioluminescant corals that can be kept in a tank? I've heard of one called a knob coral but can't seemt o find any on the internet. Looking for something to glow under my led moonlights.
There's no such thing as a truely bioluminescent coral. There's corals that'll look like it under actinics, but they're not bioluminescent. If that's what you're after, then look for green, yellow, orange, and red corals.
