I read an article that said fish do not care about lighting. So when I moved
my fish into the dark basement I made no lighting provisions. Any past
experience on fish and lighting ? The indoor pond is 4' x 4' x 3 deep 300
gallons. The water temp will be about 72° all winter. I am looking at a
cover to reduce humidity loss and hold heat in. I thought about putting a
light though the top and hanging it so the base is outside the cover and the
body is inside. This would provide some heat and lighting.
