i just read in this book i got from the library that changing light effects the fish. and on that web site they have a laser that flashes different colors. not sure with lasers though...cause the color is mostly concentrated where it hits a surface. but if it does effect fish, the changing light could b stressful
They aren't lazers they are LED's and the blue and purple don't show up all that well. The green and red work best. I use mine after lights out if I want to watch the fish for a bit. I have mine on maybe 2hr a month. My tigers like swimming in the colord lights. Yes they are very cool. They are just a steady stream of colored lights no fancy flashing or disco stuff. Rose
well the ones shown are lasers rose, not leds( i should know the difference i work with lasers lol ) they had led effect things as well, wont be getting any of either i was curious to peoples views and if they came across them before thats all.
I agree with Rose - I got LED lights in both my tanks - only put them on after lights out - makes the tanks really look good in the dark - and the fish don't seem to mind. Anyawy - can fish see colours?
