hey everyone. we all no that sometime when u turn on your fish tank light sometime your fish go crazy. well usually my atf will go a little nutso for a few second when i turn on the light. anyway this morning i turned on the lights and he went crazy and swam into wall and kept trying to swim through it. then he tried to go under the gravel then he weged him self under the drift wood. i mean i guess he wanted to sleep in or something. anyway good thing i was going into work bc i took everythink out so he couldnt hit on or wedge him self any where. well its lunch now and he is good but is a little banged up. my question is does anyone know or have any tricks to stop this. thanks who knows it could be that they just wanted to sleep in and to fix it u need to put them to bed sooner :ROFL: :screwy: .
 
In the morning, before my timer turns on the aquarium light, I turn on the light in the room. It gives the fish a low intensity light to get used to before the bright stuff turns on. I heard of some people using blue atinic. They turn those on first, then after a half hour, they turn on the day lights.
 
agreed with above, room lights slowly at first...

guess it would be like if you woke up to some flood lights in your face, i would go krazee too!

ya thats what i was thinking of doing was turning on the room light first, thanks
 
Normally the sun is out long before I turn on my aquarium lights, to cut down on algae I don't even have the lights on when I am not home. If I do turn the lights on eary though I turn on the room lights first. I made the mistake of turning on the oscar's light at 6:00 one morning and she flipped out. She banged herself up, would not eat and sulked for a number of days.
 
thanks for all the help
 
yeah cause its kind of like, when someone flashes bright light into your eyes and its dark, it like hurts them, thats why i turn them on after i come home from school, so the sun light makes them get used to the lighting a bit and there eyes adjust to the light.
 
i used to run an actinic dusk/dawn for 1 hour to kinda buffer the difference. i figured it was contributing to algae more than anything, so i axed it.

I kind of agree. I know for a fact that a fishes eyes takes longer to focus. I have heard that they do go simi-blind when you trun on the light.
