I used danios to start up a new tank. At first, they would do what you
said, hide when the lite came on. Then I put the light on a timer, goes on
at 7am for 3 hours then at 5pm for 4 hours. Also, I made it a habit to feed
them when the light came on at 7am. Now, when the light comes on, they swim
up to the surface and dart around waiting for the food to drop in.

Probably one has nothing to do with the other, but just my experience.

Hello,

I am currently using a 9 watt bulb that came with my tank. Whenever I
turn
it on, I've noticed that my danios go and hide under the power filter.
They
come out occasionally but seem not to like the light.

Should I stop using the light or will they get used to it?

Thanks.
