I keep seeing this on the tips of my digitatas and it is really cool, maybe its because of the aquapink bulb I don’t know. I’m sure there is a proper term for it but for now I’m calling it “spectral halo” lol.
Look at the edge of this coral close up. Almost need 3D glasses!
That’s pretty cool. Maybe they should market the aquapink bulbs as 3d bulbs lol. Take that tv manufacturers! I have one in my tank too and it makes my strawberry psuedochromis almost hard to look at with a similar effect when he comes out of the rockwork and into the direct light.
