Pond Boss Forums INTRO Questions & Observations Crayfish attracted to the light.

I have proven that the 365nm light won't glow the crayfish in our pond in Ontario Canada. I tried it in the water and out of the water just in case the pond dye stopped the light penetration. Even out of the pond they will not glow with the black light. Too bad I was very excited this would work.

Cheers Don.
