i was wondering if anybody has a black light over there tank, i saw a picture of a loinfish reacting to what looked like a black light but i dunno, would it be recomended or not, does the white sand react to it?? (when i say react i mean glow blue) lemme know, cause i think that would be cool. as long as it doesnt hurt the fish lol swiming into eachother all upside down into the glass not good
