My Fish Dont Like The Light

[roadman]

I have Danio choprae 5 of them otherwise known as glowlight danio

When the light is off they have a great time utilising the whole tank when i put the light on in the day they all go and huddle in a corner thats not even a hiding spot

Literally turn light off they swim about turn it on they go to this corner

Any ideas? :( i just want them to be happy but I know the fish and plants need a light to distinguish night and day
