Cool.

I just discovered something useful.

I recently got a couple of those Chinese UV (Blue LED) Flashlights to observe my SPS coral at night for Polyp Extensions, and seeing SPS glow where growth is happening.

When I shine the light on even the smallest Hydriod Poly, it's tip glows green.
I came across this discouvery tonight when I shined into my New Frag tank to check out the removed Plugs. (and there on a plug was a Hydriod glowing green, that I never saw)

This will help find them in the tank. Even the youngest starters.
