I just picked up a new marine land double bright light,when I put on the blue lights only the fish go crazy and smash into the tank.I was wondering if anyone else has had that experience.Before this light I bought a Led light with a remote that does every mode you can imagine,but the fish freaked out when the lights changed.So that is why this time I bought one that has two color spectrum's blue and white and all Blue.I cant use the all blue because they freak out.I would like to leave on as night light in blue but I cant.The light is 48 inches long and is on a 400 gallon tank 36 inches tall so need double bright because of height.Any suggestions how to get fish use to blue night light.
