i found a way to lure my perc into my Anemonea

I dont know how but i did something that automatically made my ocellaris host my seabae. This is what i did. I have this black light ballast with a 13w black light, well i place this in the tank today just to see what it did , of course this was at night, my anemonea was so cool looking. it almost acts as a moon light. Well within minutes , my ocellaris was going crazy with this anemonea it dove right in. Cool huh well if anyone has any explanations or Questions on how this happen let me now please
