Flourescent Light & Tetras

[JeromeEverall]

Hi Guys,

I've left my flourescent light off for a while, due to there being lots of sunlight about, but now, whenever I turn the light on again, all of my fish dash off and hide behind something big, and stay there permanently until I switch the light off again.

I've tried replacing the harsh white tube with a special pinkish tropical flourescent tube, but it has the same effect.

My plants are starting to die off so I was wondering if there was any gentler way to add light to my aquarium! I'm already using the miracle beam system, but I was thinking possibly a blue or UV tube? I've seen them used at commercial aquariums, but i'm not sure if they're commonly available!

Any help much appreciated

do you turn the room light on before the tank light?
sounds like a silly question I know but despite the amount of sunlight your tank gets the fish will have adjusted to that light and I expect the entensity of the tank light gives them a bit of a shock when it comes on
Try turning the room light on for a minute or two then turn on the tank light - that way there isn't a sudden light increase that may spook your fish.

I don't know if that helps or not
