white cloud mountain minnows.

ive never heard of keeping them in the dark, because they need vitamin D supplied by light

Ok Then Thanks

Will The Light In The Fish Tank Provide Vitamin D?

I have never kept them in the dark, well I do turn off the lights at night time but thats the same on all the tanks

Guppies tend to give birth at night or first thing in the morning.
But I've never heard of this either.

Guppies and most other livebearers give birth after dark so the predators can't see the newborn fry and eat them. They don't need to be kept in the dark.

Aquarium lights will not provide Vitamin D for the fish unless you have metal halides and the light units don't have UV reducing glass on it.
Fish get most of the Vit D they need from the fish food they eat. A varied diet will prevent nutritional deficiencies form occurring.

Tetras are the only fish I know of that have light sensitive eggs. The eggs of most species of tetra won't hatch if they are kept in a light environment. Therefore if you breed tetras, you should not have a light on the tank and when the parents have been removed, the tank should be covered with a towel until the eggs have hatched.

WCMM = white cloud mountain minnows.
