I actually had one. Also had an entire laser system 9made by same company) set up in my 150 that was hooked up to my stereo. So the lasers moved around like a dance club. Pretty sure fish hated it. If the lights came on the fish hid. But I was in college and was having fun. So when I got more serious into fish, I took out all the fake stuff and made it more natural. But the lasers were cool.
